Context Mode Upgrade

Pull latest from GitHub and reinstall the plugin.

Instructions

1. Call the ctx_upgrade MCP tool directly. It returns a shell command to execute.
2. Run the returned command using your shell execution tool (Bash, shell_execute, etc.).
3. Display results as a markdown checklist:

   ## context-mode upgrade
   - [x] Pulled latest from GitHub
   - [x] Built and installed v1.0.39
   - [x] Hooks configured
   - [x] Doctor: all checks PASS
   

   Use [x] for success, [ ] for failure. Show actual version numbers.
4. Tell the user to restart their session to pick up the new version.
5. Fallback (only if MCP tool call fails): Derive the plugin root from this skill's base directory (go up 2 levels — remove /skills/ctx-upgrade), then run with Bash:

   CLI="<PLUGIN_ROOT>/cli.bundle.mjs"; [ ! -f "$CLI" ] && CLI="<PLUGIN_ROOT>/build/cli.js"; node "$CLI" upgrade
