* fix(memory): await search-sync before returning results to prevent stale index
When the gateway process has been running for a while, memory_search
returns stale results because startAsyncSearchSync fires off the index
sync as a background task (void ... .catch()) without waiting for it
to complete. Search results are then read from the old index state.
Change startAsyncSearchSync from sync/fire-and-forget to async/await
so that the index is synced before search results are returned. This
ensures memory_search reflects the current filesystem state, matching
the behavior of the CLI command which creates
a fresh manager each time.
Fixes#52115
* test(memory): prove search waits for dirty sync
* test(memory): align search with synchronous sync
