[biodrone]

Summary

Major release merging staging into master, covering work since the last production release.

Features

• Twitch VOD support — new VOD download mode with per-channel config (vod: true, vod_limit), SQLite tracking database, atomic claim/complete/fail lifecycle, and yt-dlp-based VOD enumeration (feat: Twitch VOD support #551, closes [FEATURE] - Twitch VOD Support #231)
• FFmpeg retry logic and network resilience — configurable retry with exponential backoff, reconnect flags, stream copy mode, and extra input/output opts via env vars
• Health check endpoints — HTTP /health on both client and server containers
• Unit and integration tests — config reader tests, moveFile cross-device tests, end-to-end live stream download test, VOD integration test

Bug Fixes

• Fix unreachable rate-limit retry branch — replaced nested else-if with explicit retry loop (fix: rate-limit retry loop and docstring coverage #559, closes fix: unreachable rate-limit retry branch in live stream tick loop #555)
• Fix non-rate-limit errors silently swallowed on first getStream call
• Release VOD claim on setup and resolution failures

Chores

• Non-root Docker containers with proper UMASK/permissions handling
• CodeRabbit config for staging PR reviews
