feat(moderation): skip AI analysis for music bots via AI_SKIP_ANALYSIS_USER_IDS

Jockie Music (user 411916947773587456) posts now-playing embeds/spotify links
~1347 captured messages — every one consumed a moderation LLM call for zero
signal and contributed to batch timeouts. Config AI_SKIP_ANALYSIS_USER_IDS
(default=Jockie) skips them at ALL three analysis paths:
- queueMessageAnalysis entry (direct skip-result like age-restricted)
- batchScheduler processing (pre-batch filter)
- individual recovery path (no fallback spam for already-skipped authors)

Skip-result mirrors age_restricted: status=clean, flags=[skip_analysis_user],
action=none — stays visible in the dashboard, never analyzed.
