feat: v0.12.0 Settings window, per-session Remote Control, delete conversations

- Settings (⋯ → Settings…, palette): theme, terminal text size, interface size, notifications, Remote Control & privacy. The ⋯ menu shrinks. - Remote Control per session: registry choice > Settings default > DEVDESK_REMOTE_CONTROL. Switching an idle session restarts its Claude on the same conversation; busy sessions change at the next start. rc_active comes from the running process; RC tag on sessions. - --delete-convo: remove a conversation's local transcript and subagent files; refused while in use. Delete… in Search past conversations. Closes #61 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WHRLCCdXYm41Qx5kNhehaP

  - **`devdesk guests [ID|IP|NAME]`** lists Proxmox CTs/VMs with the node each runs on now, status, HA state and IPs. Claude is told to use it before acting, because HA guests move. Stopped guests keep the IP they had when last seen running.
  - Configure `DEVDESK_GRAFANA_URL`, plus a Viewer token in `DEVDESK_GRAFANA_TOKEN_FILE`. For the guest lookup, set `DEVDESK_PVE_NODES` to a few Proxmox nodes reachable by root SSH key. VM IPs need the QEMU guest agent.
 - **Repo / CI panel:** branch, ahead/behind, uncommitted changes, HEAD's Gitea CI status and open PRs for the session's folder. The first changed files are listed; click one for its diff against HEAD. When CI fails, **Ask Claude to fix CI** types a prompt to read the failed job's log.
- **Files** (Ctrl+Shift+E), laid out like VS Code: an explorer tree (git colours, gitignored entries dimmed) and an editor with tabs (a click opens a preview tab, a double-click keeps it), **Go to file** (Ctrl+P in the pane), markdown previews (sanitized, with relative images), images, and a Changes view of uncommitted files with line counts, a **C** badge on files Claude edited, and diffs against HEAD. **@Claude** types `@path` into the prompt. Tabs and open folders are remembered per session. Paths can't leave the session folder.
+- **Files** (Ctrl+Shift+E), laid out like VS Code:
+  - **Explorer tree:** git colours, gitignored entries dimmed.
+  - **Mouse:** right-click menus (new file/folder, rename, delete, cut/copy/paste, duplicate, copy path, download, @Claude), Ctrl/Shift+click to select several, drag to move (Ctrl+drag copies). Drop files or whole folders from the desktop to upload them (up to 25 MB each), or drag a file onto the terminal to type `@path`.
+  - **Keyboard:** F2 renames in place, Delete trashes, Ctrl+C/X/V copy and paste files.
+  - **Safety:** delete goes to a 7-day trash with **Undo**; nothing is overwritten unless you choose Replace.
+  - **Editor:** tabs (a click opens a preview tab, a double-click keeps it; right-click for close variants; drag to reorder), **Go to file** (Ctrl+P in the pane), and **Search in files** (Ctrl+Shift+F: match case, whole word, regex). A status bar shows line/column, cursors, indentation, line endings and language. Multiple cursors (Alt+click), column select (Alt+drag), auto-closing brackets, Ctrl+G to go to a line.
+  - **Markdown preview:** GitHub-style headings with anchors and an outline, syntax-coloured code with Copy, callouts, task lists, front matter, images, and links that open files in DevDesk. **Split** shows the source and a live preview side by side.
+  - **Changes view:** uncommitted files with line counts, a **C** badge on files Claude edited, and diffs against HEAD. **@Claude** types `@path` into the prompt.
+  - **Remembered and contained:** tabs and open folders are remembered per session, and paths can't leave the session folder.
  - **Editing:** text files are editable; ● marks unsaved tabs; Ctrl+S (or Save) writes atomically and keeps the file's mode and owner. If the file changed on disk since you opened it (Claude edited it), saving asks: Compare (a diff of disk vs yours), Overwrite or Cancel; a change on disk while you edit shows a banner instead of replacing your text. Unsaved edits are kept as drafts in the browser, so a reload or a session switch doesn't lose them. ＋ creates a file (folders as needed). The editor bundle (`/usr/share/devdesk/assets/editor.js`) loads over ttyd the first time and is cached by the browser.
 - **Paths are links:** a file path Claude prints (`web/src/files.js`, `notes.md:12`) opens in Files when clicked, at that line if given.
 - **Ops guard:** `devdesk-guard` (a PreToolUse hook) makes Claude ask before destructive commands (`pct destroy`, `zfs destroy`, Ceph pool/OSD removal, `rm -r /…`, `git push --force`, `reboot`…), even in auto mode. `DEVDESK_GUARD=0` turns it off; `/etc/devdesk/guard.local` adds rules (`regex<TAB>reason`). Bash commands are logged per session, and sessions are tagged with the hosts they touch (ssh targets, CT/VM ids).
 - **Search past conversations** (⋯ menu, palette): full text over every Claude conversation on the host; **Resume** it in a new session or **Fork** it.
 - **Plan usage:** the 5-hour and weekly windows as meters in the footer, with when each resets (`↻ 14:30`). If the pace so far would use a window up before it resets, the meter shows `⚠ full ~13:50` instead. A toast warns at 90 %, and Matrix gets one message per window when you're away (`DEVDESK_USAGE_WARN`). Sessions also get a **PR** chip when their branch has a pull request.
+- **Settings** (⋯ → Settings…): theme, terminal text size and interface size (per browser), desktop notifications, and **Remote Control per session**. With Remote Control on, a session also shows in the Claude app and at claude.ai/code, and Anthropic stores its transcript to sync devices (30 days, or 5 years if "Help improve Claude" is on). It's **off for new sessions** unless you change the default. Each running session has its own switch, which restarts that Claude on the same conversation when it's idle. Sessions that sync show an **RC** tag.
+- **Delete a conversation:** Search past conversations → **Delete…** removes its local transcript (`~/.claude/projects`) for good; a copy synced by Remote Control is deleted at claude.ai/code.
 - **Quiet phone at the desk:** while a tab shows a session, Remote Control holds back phone pushes for it (client-presence marker, expires ~2 min after you leave).
 - **Context:** a Claude `statusLine` command (`devdesk-statusline`) snapshots each session's model, context-window use, plan usage and cost to `/var/lib/devdesk/context/<session>.json`. The Sessions panel shows it as a bar and Claude's own footer shows a one-line summary. On a Pro/Max plan that summary shows 5-hour plan usage; the dollar figure Claude reports there is an API-price estimate, not a bill, so it appears only for API-key billing.
 - **Light mode:** the terminal switches palettes with the page. DevDesk starts Claude with its `dark-ansi` theme so Claude draws with the terminal's 16 colours, and the light palette maps bright white to ink; tmux and the status line use ANSI colours too. A session picks up Claude's theme the next time Claude starts in it (`/exit`, then ⏎ resumes the same conversation).

 The **☀/◐** button switches light and dark mode (saved per browser, shared with the other web_template apps' `lt_theme` preference). Text size, desktop notifications (with a mute), the keyboard shortcuts sheet and fullscreen are in the **⋯** menu; everything is also in the command palette. In Chromium, fullscreen also captures Ctrl+W/Ctrl+T, which browsers otherwise keep for themselves.

 - `/etc/devdesk/env` holds the packaged defaults; don't edit it. Its keys:
  - port, bind address, projects root and `DEVDESK_DEFAULT_DIR`
  - `DEVDESK_GITEA_URL` / `DEVDESK_GITEA_ALIASES` for the Repo/CI panel. Public repos need no token; for private ones put a `read:repository` token in `/etc/devdesk/gitea-token`
  - `CLAUDE_BIN` and `CLAUDE_ARGS`

jaredandClaude Opus 5.5	20134c1e58	feat: v0.12.0 Settings window, per-session Remote Control, delete conversations build-deb / Lint, test, package (push) Successful in 4m59s Details build-deb / Deploy to CT 126 (push) Successful in 14s Details build-deb / Notify on failure (push) Skipped Details - Settings (⋯ → Settings…, palette): theme, terminal text size, interface size, notifications, Remote Control & privacy. The ⋯ menu shrinks. - Remote Control per session: registry choice > Settings default > DEVDESK_REMOTE_CONTROL. Switching an idle session restarts its Claude on the same conversation; busy sessions change at the next start. rc_active comes from the running process; RC tag on sessions. - --delete-convo: remove a conversation's local transcript and subagent files; refused while in use. Delete… in Search past conversations.

jaredandClaude Opus 5.5	65114165e7	feat: v0.11.0 VS Code-like explorer, markdown preview, search in files build-deb / Lint, test, package (push) Successful in 2m29s Details build-deb / Deploy to CT 126 (push) Successful in 7s Details build-deb / Notify on failure (push) Skipped Details - Explorer: context menus, multi-select, inline rename/new, drag to move or copy, desktop drag-and-drop uploads (folders too), cut/copy/paste, duplicate, download, delete to a 7-day trash with Undo. Server side in libexec/devdesk-fsops.sh with bats tests. Closes #54 - Markdown preview in a shadow root: headings with anchors and outline, highlighted code with copy, callouts, task lists, front matter, links that open files, live split view. Editor status bar, multi-cursor, closeBrackets, Ctrl+G, tab menus and reordering. Closes #55 - Search in files (Ctrl+Shift+F) via git grep / grep. Closes #56 - Fix: nested $(...) path checks now fail hard (set -e does not reach them; an escape created /x in testing); newest folder listing wins; sessionAction returns the reply JSON.

jaredandClaude Opus 5.5	e60f1ad066	fix: v0.10.4 session list scrolls on its own build-deb / Lint, test, package (push) Successful in 3m13s Details build-deb / Deploy to CT 126 (push) Successful in 13s Details build-deb / Notify on failure (push) Skipped Details No cap on sessions existed, but only the whole Panels column scrolled, so many sessions pushed Ops Alerts and Repo/CI far down. The list now has its own scroll area (46vh), keeps its position across polls and brings the current session into view on switch.

jaredandClaude Opus 5.5	ab7e127f70	fix: v0.10.3 no tmux right-click menus; close split panes build-deb / Deploy to CT 126 (push) Successful in 19s Details build-deb / Lint, test, package (push) Successful in 3m9s Details build-deb / Notify on failure (push) Skipped Details Right-clicking a pane opened tmux's menu, whose Split entries left a stray pane next to Claude (and whose Kill entries could end it). Unbind the right-click menus; add --unsplit and a palette entry that closes extra panes and keeps Claude's.
