feat: free-form sessions, rename/end from the panel, live Claude Context (0.2.0)

- Sessions no longer need a project folder: any name works and starts in
  DEVDESK_DEFAULT_DIR unless it matches a project; `devdesk new NAME [PROJECT]`.
- Rename (✎) and end/forget (×) sessions from the Sessions panel, plus
  `devdesk rename`. The browser runs them as `devdesk attach --new|--rename|--end`
  through ttyd. Renames keep the running Claude and its recorded conversation:
  the hook, the run-wrapper and the statusline ask tmux for the current name.
- Claude Context panel is live: devdesk-statusline snapshots model,
  context-window use, cost and edits per session, which --list reports;
  Claude's footer gets a one-line summary. The panel now sits under Sessions.

 - **Only `systemctl stop devdesk-tmux` (or removing the package) ends the sessions.**
 
 ## Sessions
-- **How the session is chosen:**
-  - `https://dev.lotusguild.org/?arg=<name>` opens session `<name>` and creates it on demand in `$DEVDESK_PROJECTS_ROOT/<name>`. `main` uses the root itself, and folders with spaces are reached by slug (`test code` → `test-code`).
+- **Any name works.** Sessions don't have to be repo work:
+  - A name matching a project folder (`tinker_tickets`, or `test-code` for `test code`) starts there.
+  - Anything else (`pbs-upgrade`, `ceph-check`) starts in `$DEVDESK_DEFAULT_DIR`, which is `/root/code` by default.
+  - `main` is the projects root.
+- **Opening one:**
+  - `https://dev.lotusguild.org/?arg=<name>` opens or creates that session.
   - With no `?arg=`, an fzf picker opens, listing running (●), dormant (○) and new (+) sessions.
+  - The **Sessions** panel's form takes any name plus an optional project folder.
+- **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.
-- **SSH:** `devdesk attach <name>`, `devdesk ls`, `devdesk pick`, `devdesk end <name>`.
+- **Claude Context panel:** a Claude `statusLine` command (`devdesk-statusline`) snapshots each session's model, context-window use, cost and edits to `/var/lib/devdesk/context/<session>.json`. The panel shows the current session's numbers, and Claude's own footer shows a one-line summary. Sessions started before 0.2.0 need Claude restarted (`/exit`, then ⏎ in the menu) before they report.
+- **SSH:** `devdesk attach <name>`, `devdesk new <name> [project]`, `devdesk rename <old> <new>`, `devdesk end <name>`, `devdesk ls`, `devdesk pick`.
