Context Mode Purge

Permanently deletes session data for this project. Two scopes are supported (issue #520):

• Project scope (scope: "project"): wipes EVERYTHING, knowledge base, all session DB rows for every session, events markdown, and stats.
• Session scope (sessionId: "<id>" or scope: "session"): wipes ONLY the matching session's rows + FTS5 chunks. Sibling sessions, project stats, and the FTS5 store file are preserved.

Instructions

1. Decide the scope first with the user:
   • "Wipe just one session?" → ask for the sessionId.
   • "Wipe the whole project?" → confirm scope:'project' (this is the destructive, irreversible default).
2. Warn the user about scope:'project'. Everything will be deleted:
   • FTS5 knowledge base (all indexed content from ctx_index, ctx_fetch_and_index, ctx_batch_execute)
   • Session events DB (analytics, metadata, resume snapshots) for ALL sessions in the project
   • Session events markdown file
   • In-memory session stats + persisted stats file
3. Call the mcp__context-mode__ctx_purge MCP tool with the chosen parameters:
   • Scoped: { confirm: true, sessionId: "<id>" }, implies scope:'session'.
   • Project: { confirm: true, scope: "project" }, explicit destructive form.
   • Bare { confirm: true } still works but emits a deprecation warning. Prefer the explicit forms.
4. Report the result to the user, the response lists exactly what was deleted and (for scoped purges) confirms that other sessions and project stats were preserved.

Schema rules

• confirm: true is always required.
• sessionId and scope: "project" together is REJECTED as ambiguous (the sessionId implies session scope; combining with project scope contradicts intent).
• scope: "session" without sessionId throws, sessionId is required.
