## Summary
- **Make app-synced objects searchable**: `isSearchable` was hardcoded
to `false` and the `searchVector` field was missing the `GENERATED
ALWAYS AS (...)` expression, causing all records to have a `NULL` search
vector and be excluded from search results. Fixed by defaulting
`isSearchable` to `true` (configurable via the object manifest),
computing the `asExpression` from the label identifier field, and
allowing the update-field-action-handler to handle the `null` → defined
`asExpression` transition.
- **Make `isSearchable` updatable on an object**: The property had
`toCompare: false` in the entity properties configuration, so updates
via the API were silently ignored and never persisted. Fixed by setting
`toCompare: true`.
- `frontComponentHostCommunicationApi` gets a new object reference on
every render, causing the `useMemo`/`useEffect` in
`FrontComponentWorkerEffect` to tear down and re-create the web worker
each time.
- Decouple the host API lifecycle from the worker lifecycle by moving
thread.exports updates into a dedicated
`FrontComponentUpdateHostCommunicationApiEffect` that mutates the
thread's exports object in place via Object.assign.
- Rename `FrontComponentHostCommunicationApiEffect` to
`FrontComponentInitializeHostCommunicationApiEffect` for clarity.
