v2.2.0

Safety fixes across the installer, the uninstaller, and the compress skill.

Install / uninstall

• Uninstall no longer deletes hook files while settings.json still points at them — that is #471 on every session start. A settings file it cannot parse or rewrite is now a hard stop, and the POSIX and PowerShell uninstallers exit non-zero on a missing node for the same reason.
• Install leaves another plugin's hooks/package.json alone; uninstall removes only the manifest caveman ships.
• Installer temp downloads move to a 0700 mkdtemp, so a pre-planted symlink can no longer capture the init script the installer then executes.
• The binary installers give each download its own .part. The fixed name made the O_EXCL guard unreachable, letting concurrent installs publish each other's half-written files as "checksum verified".

Compress skill

• The outer-fence strip no longer merges a document's first and last code blocks into prose. It matched any file that merely started and ended with a fence line.
• The validator now sees CommonMark indented code blocks — a 4-space-indented kubectl delete was prose to it, so a rewritten destructive command passed clean and overwrote the file.
• Lost file paths and renamed headings are errors, not warnings that let the in-place overwrite stand.

Hooks

• cavecrew model overrides no longer rewrite tracked agents/*.md when the plugin root is a source checkout.

Benchmarks

• benchmarks/run.py gains a terse control arm, so the next regenerated table separates what the skill adds from what any "answer concisely" instruction already buys. The published 65% is against an unprompted baseline and now says so.
