Record the git dirty hash during watcher baseline so an already-dirty worktree registered after explicit MCP indexing is not treated as a new change on the next watcher poll. This prevents watcher-driven full reindex from mutating the project DB after index_repository has returned.
Also preserve adaptive backoff after normal baseline snapshots while still honoring a real touch during an in-flight poll by recording the snapshot's original next_poll_ns.
