feat(assistant): run update-bulletin job on daemon startup

[siddseethepalli]

Summary

• Swaps the blocking syncUpdateBulletinOnStartup() call in the daemon startup path for a fire-and-forget dynamic import of runUpdateBulletinJobIfNeeded(). The job module is only loaded once dbReady is true.
• Respects the daemon-never-blocks-startup invariant: any failure is logged at warn and startup continues.

Part of plan: updates-md-background-job.md (PR 5 of 9)
