Adds a core sessions_search agent tool backed by a SQLite FTS5 index that
lives next to the transcript rows in the per-agent database. Indexing is
transactional: user/assistant text is indexed inside the same write
transaction that persists the event, deletes drop index rows in the same
transaction, and branch rewinds mark the session dirty so the next search
rebuilds it from the same visible-path resolution sessions_history uses
(which also lazily backfills doctor-migrated databases). Search executes
gateway-side behind an additive sessions.search method with a bounded
session-key allowlist; visibility, sandbox restrictions, and snippet
redaction mirror sessions_history.
Closes#100978
Fixes#89691.
Memory search now treats explicitly configured non-local embedding providers as required. When that provider is unavailable, search and sync surface an unavailable memory-search result instead of silently returning FTS-only recall.
Unset/default/local/none-style paths keep FTS fallback so existing workflows do not lose keyword recall entirely. The fallback state is now surfaced in diagnostics/status instead of being hidden.
Maintainer merge note: current CI still has unrelated baseline boundary failures in extensions/google/google.live.test.ts and extensions/minimax/minimax.live.test.ts. This PR does not touch those files; the PR-specific memory, docs, lint, type, security, and ClawSweeper checks were reviewed before merge.
Simplify plugin installation and runtime loading around package-manager-owned dependencies, with Jiti reserved for local/TS fallback paths.
Also scans npm plugin install roots so hoisted transitive dependencies are covered by dependency denylist and node_modules symlink checks.
