Michael SuchaczandCoder Agents 6bb88775ab test(coderd/x/chatd): pin TestGetWorkspaceConn_StatusCheck to mock clock (#25130)
The `TimedOutAgentCacheHit`, `CacheHitHealthyAgent`, and
`CacheHitDBError` subtests of `TestGetWorkspaceConn_StatusCheck` built
their `WorkspaceAgent` timestamps with `time.Now()` in the parent test's
slice literal and then ran the actual check against the server's real
wall clock (`quartz.NewReal()`). On slow Windows CI runners, more than
`agentInactiveDisconnectTimeout` (30s) of wall time can elapse between
slice construction and the parallel subtest body. In that window, the
cached "healthy" agent gets reclassified as disconnected by
`agentDisconnectedFor`, and `CacheHitHealthyAgent` fails with
`errChatAgentDisconnected` instead of returning the cached connection.

Build each agent inside the subtest with `quartz.NewMock(t)` and feed
the same clock into the `Server` so the agent timestamps and the status
math share a single frozen `now`. This matches the pattern already used
by `TestGetWorkspaceConn_DialTimeoutDisconnectedRecoveryThreshold` in
the same file.

Closes https://github.com/coder/internal/issues/1522

<summary>Verification</summary>

Inserting `time.Sleep(35 * time.Second)` at the top of each subtest's
body reliably reproduces the original failure
(`errChatAgentDisconnected` on `CacheHitHealthyAgent`) on the parent
commit and passes with this change. After removing the synthetic sleep,
`go test ./coderd/x/chatd -run TestGetWorkspaceConn_StatusCheck
-count=50` passes cleanly.
