feat: v0.10.0 quieter Matrix, worktrees, usage pace, repo diffs, copy reply, turn timer, compact

- Matrix "needs you": ignore Claude's idle reminder (no red, no post); post
  only when no tab is in view, after 60 s, once per session per 10 min, and
  say what is asked. Closes #50
- devdesk new NAME PROJECT --worktree: own checkout on devdesk/NAME,
  cleaned up on end when clean/merged. Closes #44
- Usage meters: reset time, pace warning; Matrix ping past 90% when away.
  Closes #45
- Repo panel lists changed files; click opens the diff. Closes #46
- Copy Claude's last reply (--last-reply). Closes #47
- Turn timer in chip, title and cards. Closes #48
- Compact button at 80% context when idle. Closes #49

   - With no `?arg=`, DevDesk reattaches the session you used last in this browser (or the most recently active one). The fzf picker, listing running (●), dormant (○) and new (+) sessions, is under the session chip's menu.
   - **Session chip** (header): click to switch sessions; its dot shows Claude's state.
   - **+ New** in the Sessions panel takes any name plus an optional project folder.
+- **Own git worktree:** for a git project, tick **own git worktree** (or `devdesk new NAME PROJECT --worktree`). The session gets its own checkout in `$ROOT/.worktrees/PROJECT--NAME` on branch `devdesk/NAME`, so two Claudes on one repo never edit the same files. Ending it removes the worktree only if nothing is uncommitted, and the branch only if it's merged.
 - **Rename / end:** the ✎ and × buttons on each session in the panel. Renaming keeps the session, its running Claude and its recorded conversation. Ending stops Claude; the conversation stays in Claude's history.
 - **Windows:** each session has a `claude` window (0) and a `shell` window (1).
 - **Conversation tracking:** a Claude `SessionStart` hook records each session's conversation ID in `/var/lib/devdesk/registry.json`. After a reboot the session resumes *that* conversation, even when other Claude instances, such as code-server, use the same directory.
-- **Session status:** Claude hooks (`devdesk-state-hook`) mark each session **working**, **waiting on you** (with Claude's message) or **idle**.
+- **Session status:** Claude hooks (`devdesk-state-hook`) mark each session **working**, **waiting on you** (with Claude's message) or **idle**. Claude's idle reminder a minute after a turn ends doesn't count as waiting. While Claude works, the session chip and the tab title show how long the turn has run (`⏳ 3m`).
+- **Session buttons:** ⧉ copies Claude's whole last reply as Markdown. ⇲ **Compact** appears when the context is 80 % full and Claude is idle, and sends `/compact`.
   - The sidebar shows it with context % and a context bar; the session chip's dot shows the current session's state.
   - A "… needs you" chip jumps to other sessions that are waiting, and a desktop notification fires when one starts waiting.
   - The **🔔 inbox** lists what needs you (waiting sessions, firing Grafana alerts) and what happened while you were away (a background session finished or started waiting, CI passed or failed); its badge counts them.
   - **Answer from the inbox:** a session waiting on a permission shows the exact command/file and **Allow / Deny** (the key is pressed only if that prompt is still on screen); other waits and finished sessions offer **Peek & reply**: the last exchange and a reply box.
-- **Matrix "Claude needs you":** when a session has waited for `DEVDESK_MATRIX_DELAY` seconds (30) and no browser tab or SSH client is attached to it, `devdesk-notify-matrix` posts one message per wait, with a link, to the hookshot webhook URL in `/etc/devdesk/matrix-webhook` (mode 600; no file = off).
+- **Matrix "Claude needs you":** when a session has waited on a real request (a permission prompt or a question) for `DEVDESK_MATRIX_DELAY` seconds (60) and no DevDesk tab has been in view for about 2 minutes, `devdesk-notify-matrix` posts what Claude asks ("alpha: Claude wants to run Bash (Restart nginx)", the command, a link). The post goes to the hookshot webhook URL in `/etc/devdesk/matrix-webhook` (mode 600; no file = off). Each session posts at most once per `DEVDESK_MATRIX_QUIET` seconds (600).
 - **File & image drop:** drag files onto the terminal or paste a screenshot.
   - They're uploaded through ttyd to `/var/lib/devdesk/uploads/<session>/` (25 MB max, pruned after 7 days), and the path is pasted into Claude.
   - For images, Claude attaches them itself.

   - Guests are matched by the alert's `instance` IP (or host name), else by name in the job or alert ("by name"). Aggregate rules with no labels (`count(up == 0)`) get a hint to run the inner query instead.
   - **`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. When CI fails, **Ask Claude to fix CI** types a prompt to read the failed job's log.
+- **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.
   - **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 (warning at 90 %); a **PR** chip on sessions whose branch has a pull request.
+- **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.
 - **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).
 - **Phone:** a key bar replaces the shortcut hints (Esc, Tab, ⇧Tab, ^C, ↑, ↓, ⏎, Claude/Shell window), and the panels open as a drawer.
-- **SSH:** `devdesk attach <name>`, `devdesk new <name> [project]`, `devdesk rename <old> <new>`, `devdesk end <name>`, `devdesk ls`, `devdesk pick`, `devdesk repo <name>`, `devdesk alerts`.
+- **SSH:** `devdesk attach <name>`, `devdesk new <name> [project] [--worktree]`, `devdesk rename <old> <new>`, `devdesk end <name>`, `devdesk ls`, `devdesk pick`, `devdesk repo <name>`, `devdesk alerts`.
