Release v4.4.0

Modaliser v4.4.0

The Grove Leaf action now clears stale task tabs left behind when Grove
renames, moves, or deletes task files, then reveals the current task as before.
Cleanup also runs when no live task remains or the grove directory is gone.

Only clean, missing Grove task tabs from the initiating workspace are eligible,
including Markdown previews and tabs open in multiple editor groups. Existing
files, unsaved edits, unrelated deleted files, and other workspaces' tabs remain
open. Cleanup preserves focus and leaves tabs alone when a file check is uncertain.

Adoption

1. Install Modaliser v4.4.0.
2. Use Install VSCode Companion to install the bundled companion 1.1.0,
   then restart VSCode.
3. Copy the updated Grove Leaf composition and its imports from
   ~/.config/modaliser/sys/scheme/examples/vscode.scm into your own config,
   then relaunch Modaliser.

Your existing config is not rewritten by an upgrade. Older companions continue
to support listing and focusing; without the updated companion, task reveal
still works but stale tabs are not cleaned up.
