v2026.10.2 — the published schema loads

The nightly snapshot's schema.sql now loads into an empty database: it no longer repeats the full-text index's shadow tables, which made it stop at "table already exists". A forward pass logs its duration and says when it overruns its interval; the MCP recent_activity description states its 366-day window; a failed migration script rolls back. No migration, no index rebuild: deploy by tag.
