test: add vitest tests for thread_ts null check fix (#4413)

Tests verify that string thread IDs (Slack thread_ts) are correctly
included in queue routing keys and found in item searches. Covers
the regression where typeof === 'number' silently ignored string IDs,
collapsing different Slack threads into the same routing key.

+/**
+ * Tests for PR #4413: thread_ts null check fix.
+ *
+ * The queue drain logic uses `hasCrossChannelItems` with a key resolver that
+ * includes threadId in the routing key. Previously it used
+ * `typeof threadId === "number"` which silently ignored string thread IDs
+ * (e.g. Slack's `thread_ts = "1706000000.000100"`). The fix uses
+ * `threadId != null` to handle both number and string thread IDs.
