…_plan MCP tools
Exposes the foraging pipeline to MCP clients with three new tools and
wires a kind/metadata filter into `MemoryStore.search` so scoped
queries stay out of the main search surface.
MCP tools (registered in `apps/mcp-server/src/tools/foraging.ts`):
- `examples_list({ repo_root })` — compact rows (example_name,
manifest_kind, observation_count, last_scanned_at).
- `examples_query({ query, example_name?, limit? })` — BM25 hits
scoped to `kind = 'foraged-pattern'`, optionally narrowed to one
example. Snippets only — full bodies via `get_observations`.
- `examples_integrate_plan({ repo_root, example_name, target_hint? })`
— deterministic plan: npm dependency delta, files_to_copy from
indexed entrypoints, npm script config_steps, and
uncertainty_notes for everything the planner couldn't resolve.
Core surface:
- `MemoryStore.search(query, limit?, embedder?, filter?)` now accepts
`{ kind?: string; metadata?: Record<string, string> }`. When a
filter is set we skip vector re-rank — the embedding index has no
kind column, so mixing vector hits would require a second pass to
drop the off-kind rows.
- `Storage.searchFts(query, limit, filter?)` applies the filter in
SQL via `json_extract` so the LIMIT still bounds the scan.
Foraging surface:
- `buildIntegrationPlan(storage, opts)` — pure function. Reads
manifests fresh from disk rather than from the compressed
observation content (JSON is not round-trip safe through the
compressor).
CLI commands and SessionStart hook wiring arrive in the next PR.

…_plan (#46) Fills the contract gap between the merged foraging PRs (#41, #43, #44, #45) and CLAUDE.md's 'new MCP tool → update docs/mcp.md' rule. Each entry lists inputs, return shape, and the non-obvious semantics (vector re-rank skipped when filter is set; dependency_delta only computed for npm; target_hint path resolution).
