feat(music): autoplay default-on and cross-session deduplication

[LucasSantana-Dev]

Summary

• Default autoplay to enabled when no guild settings exist (was silently defaulting to disabled, causing confusion for new guilds)
• Deduplicate against persistent track history (last 20 tracks from DB) when replenishing queue, preventing recently-played songs from being re-suggested cross-session
• Fix autoplay spec tests to reflect new default-on behavior
• Add trackHistoryService mock to queueManipulation.spec.ts

Test plan

• All 14 autoplay.spec.ts tests pass
• All 37 queueManipulation.spec.ts tests pass
• CI green

Summary by CodeRabbit

• New Features

  • Enhanced automatic music queue refilling with improved duplicate prevention leveraging persistent track history for better filtering

• Behavior Updates

  • Autoplay now defaults to enabled when no prior settings exist, providing a better first-time user experience

📝 Walkthrough

Walkthrough

Updated autoplay command to default to enabled state when queue is null and settings are missing, and enhanced queue replenishment to filter duplicate candidates using persistent track history fetched from the track history service.

Changes

Cohort / File(s)	Summary
Autoplay Command packages/bot/src/functions/music/commands/autoplay.ts, packages/bot/src/functions/music/commands/autoplay.spec.ts	Changed resolveCurrentAutoplayState default return value from false to true when no guild settings exist. Updated test expectations to reflect that autoplay is now disabled by default (treating enabled as the fallback), and removed embed description assertion for the no-queue scenario.
Queue Manipulation packages/bot/src/utils/music/queueManipulation.ts, packages/bot/src/utils/music/queueManipulation.spec.ts	Added persistent track history fetching via trackHistoryService.getTrackHistory(queue.guild.id, 20) in replenishQueue. Extended buildExcludedUrls and buildExcludedKeys helper functions with optional persistentHistory parameters to incorporate historical track data into duplicate candidate filtering. Updated test setup to mock and reset track history calls.
