Patrick Buckley 3e4c1931a1 fix(storage): scope conversation-history search by project tenancy
search_history / search_history_recent searched every workstream's rows
regardless of who asked. Pre-projects that matched the trusted-team
deployment shape; with private projects (062) it became a cross-tenant
read — the recall tool and /history returned private-project rows to
non-members.

Both methods take a keyword-only user_id (protocol, sqlite, postgresql)
scoped by one portable SQL predicate (HISTORY_VISIBILITY_SCOPE_SQL)
mirroring WorkstreamProjectVisibility: a row hides only when its
workstream links to an existing private project and the user is neither
the workstream creator, the project owner, nor a member. Applied in SQL
so limit/offset pagination stays honest; COALESCE guards the
NULL-creator row, which plain <> would leak.

The recall tool pins the scope identity at prepare time (the mcp_user_id
discipline) and fails loudly on an unpinned item; /history scopes to the
acting user; user_id=None (single-user CLI lanes) stays unscoped.

Tests: cross-backend visibility matrix, ws_visible parity pin,
marker-exclusion composition, LIKE-fallback path, prepare-pin plumbing.
