Additional notes for reviewers

Hooks + skills + an MCP server entry, all pointing at the deja binary (brew install deja-vu / go install). The plugin never downloads or installs software itself: with the binary absent the SessionStart hook prints one line saying how to install it and every hook exits 0. Reads session files under the user's home only, writes an index under ~/.cache/deja, no network calls; credentials redacted at index time. Security model: docs/SECURITY-MODEL.md; the plugin dir has its own SECURITY.md. Installed and listed by copilot plugin list from a direct repo install. The reviewed ref is the tag copilot-plugin-0.19.2 (the intake clones by branch/tag, so a bare SHA in the ref field cannot be checked out); it points at main after adding claude-plugin/plugin.json in the Agent Plugins layout (the intake's first pass asked for it); the manifest there is 0.19.2, the version submitted.
