Add a distinct negative case for the SQL wake rule.

This test checks only one side of the isLimitedWake predicate. The wake run is a notification run that completes before resetAt. An error in the SQL predicate could still pass. Examples are <= written as <, a missing first-input check, or a dropped status = 'completed' check. The SQL rule duplicates the shared usageLimitBlockedRun rule, so the two can drift.

Extend this scenario instead of adding a new test. Before the cleanup, move the wake run's completedAt past the failure's resetAt. Assert that the wake run then becomes latestRunId in both threadShellFromProjection and getShellSnapshot. A user-message-started run completing before resetAt is a second near-miss to cover.

Based on learnings: "check that the test fixtures include at least one record that matches a similar-but-distinct condition ... and assert it is preserved". As per path instructions: "Extend before you add" and request tests only when they "would catch a real regression".

Narrow the holdStoppedThread read. It now loads every user_message item of the thread.

Stop previously loaded only the error items of one run. It now loads all user_message, error and notification items of the thread. Each user_message item carries its text and attachments. On a long thread, this makes Stop slower. Stop must stay responsive.

usageLimitBlockedRun needs only the error items and the first input of each run after the limited run. Read the error items first. Then read the inputs only for the later runs.
