Alejandro Gutiérrez 60c74d9463 fix(broker): shareContext stable upsert key + createStream atomic upsert ...

- shareContext: adds optional memberId param; when provided, upserts on
  (meshId, memberId) instead of (meshId, presenceId) — prevents stale
  context rows accumulating on every reconnect. Falls back to presenceId
  for legacy/anonymous connections. Also refreshes presenceId on update
  so it stays current.
- schema: adds member_id column + unique index context_mesh_member_idx
  on mesh.context table; new migration 0013_context-stable-member-key.sql.
- index.ts call site updated to pass conn.memberId as the stable key.
- createStream: replaces SELECT-then-INSERT TOCTOU race with atomic
  INSERT ... ON CONFLICT DO NOTHING RETURNING, followed by SELECT on miss.
