feat: profile-tagged session isolation (closes #323)

Add profile column to sessions table for data-level profile isolation.
All session queries now accept an optional profile filter.

Changes:
- Schema v7: new 'profile' TEXT column + idx_sessions_profile index
- Migration v7: ALTER TABLE + CREATE INDEX on existing DBs
- create_session(): new profile parameter
- ensure_session(): new profile parameter
- list_sessions_rich(): profile filter (WHERE s.profile = ?)
- search_sessions(): profile filter
- session_count(): profile filter

Sessions without a profile (None) remain visible to all queries for
backward compatibility. When a profile is passed, only that profile's
sessions are returned.

Profile agents can no longer see each other's sessions when filtered.
No breaking changes to existing callers.
