fix: v0.9.4 inbox badge clears when seen

Opening the bell marks its events seen; viewing a session (or returning to the tab) reads that session's events. The badge now drops to what is live instead of climbing with every background "finished". Closes #42 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WHRLCCdXYm41Qx5kNhehaP
fix: v0.9.3 plan usage instead of API-price cost; larger footer

 - **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.
- **Ops Alerts panel:** firing and pending Grafana alert rules, each with a link to the rule.
-  - **Ask Claude** types an investigation prompt into the current session without sending it.
-  - Configure `DEVDESK_GRAFANA_URL`, plus a Viewer token in `DEVDESK_GRAFANA_TOKEN_FILE`.
+- **Ops Alerts panel:** firing and pending Grafana alert rules, each with a link to the rule and the Proxmox guest or node it's about, e.g. `→ CT 110 draupnir · monitor-02 · stopped`.
+  - **Ask Claude** starts Claude in a new session (`alert-<name>`) with the investigation already sent. The prompt has the rule, its query, summary and labels, and where it runs: the CT/VM id, the node it's on right now, and the `ssh <node> pct exec <id> --` line. Clicking it again just opens that session.
+  - 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.
 - **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).
- **Context:** a Claude `statusLine` command (`devdesk-statusline`) snapshots each session's model, context-window use and cost to `/var/lib/devdesk/context/<session>.json`. The Sessions panel shows it as a bar (cost in the tooltip), and Claude's own footer shows a one-line summary.
+- **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.
+- **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`.

+  * Robustness (#12):
+    - A resume that fails (an early Ctrl+C, a network error) no longer

+      starts fresh only when the conversation's file is really gone;
+      otherwise the menu offers to try again.
+    - The SessionStart hook reads the session name under the registry lock
+      that rename holds, so renaming during /clear or a restart can't leave
+      the conversation id under the old name.
+    - Env files are parsed the way systemd parses them instead of being
+      sourced: values are literal (no $ expansion or command substitution),
+      and bad lines are reported and skipped.
+    - Deploys wait for the dpkg lock (120 s), log an explicit "deploy
+      FAILED" line, and the webhook answers with the result, so CI's deploy
+      job fails (and alerts) when the install fails. The deploy log is
+      rotated monthly.

+      upgrades before 0.3.1.
+    - Temp files of hooks killed mid-write are swept.

The server looks the alert up, writes the prompt and starts Claude in a new alert-<name> session with it as the first prompt, already sent. Prompts are stored in prompts/<session>.txt and consumed once by devdesk-claude-run. A session that is already running is just opened. - The prompt has the rule, query, summary, details and labels, and where it runs: the CT/VM id, the node it is on now, status and HA state, and `ssh <node> pct exec <id> --`. It reminds Claude that HA guests move (`devdesk guests <id>`), and gives aggregate rules a hint. - `devdesk guests`: Proxmox inventory over SSH (DEVDESK_PVE_NODES). pvesh gives the cluster view; each node gives lxc-info and guest-agent IPs. Cached in guests.json, keeping last-seen IPs for stopped guests; --alerts refreshes it in the background every 5 minutes. - Alerts carry uid, query, description and targets, matched by instance IP/host or by name; each card shows the target. - cmd_alerts moves to libexec/devdesk-ops.sh.
