feat: release TypeType 1.5.0

[Priveetee]

Summary

• prepare TypeType 1.5.0 across Frontend, Server, Token, Downloader, Player and Docs
• publish the 1.5.0 release notes
• add private RSS feeds and new-upload notifications
• add live-content controls to subscription feeds
• harden the public media proxy
• improve SABR resumes and long-distance seeks
• thank the current GitHub Sponsors in the main README
• advance every component pin to its reviewed main revision

Production behavior

• each account can create revocable RSS feeds for all or selected subscriptions
• administrators control RSS availability, public URL, polling and limits
• accounts can hide live and upcoming content from subscription feeds
• stale live entries no longer remain in the feed
• the public proxy accepts only supported provider media destinations
• Safari resumes and distant SABR seeks preserve position and playback intent
• the frontend uses @typetype/mse 0.1.44

Deployment requirements

• no manual database migration is required
• RSS remains disabled by default until an administrator enables it
• configure the public RSS base URL before enabling feeds
• pull and recreate the stable Compose stack after all 1.5.0 component images are published

Tests

Frontend, Server, Token, Downloader and Player CI workflows are the component release gates. Central stack CI is the final release gate. No additional local test suite was run for this release promotion.
