feat: add HLS playback support with hls.js and modular viewer architecture
CI / test (pull_request) Successful in 23s
This PR adds end-to-end HLS stream detection, interception, and playback
to the viewer. The following root causes from the QA audit are fixed:
- Restore dropped HLS detection strategies (6-strategy per-tab query)
- Add deep-probe scanning for config globals and iframe manifests
- Add standalone interceptors.js for CSP-compliant runtime injection
- Fix viewer.js string entry handling for legacy storage entries
- Fix manifest.json web_accessible_resources for interceptors.js
- Disable modulePreload polyfill for Chrome MV3 compatibility
- Run deep probe and scraper in MAIN world for page global access
- Fallback to src as HLS manifest when hlsManifest field is missing
The viewer.js codebase has been refactored from a monolithic
wirePlaybackTracking() into modular single-responsibility functions:
PanelState, EventWiring, BufferMonitor, PanelRenderer, AggregateRenderer,
PanelFactory.
Additionally:
- Remove debug console.log statements from production code
- Fix dead code in m3u8DeepProbeFn walk() that prevented config global
manifest detection
- Add eslint config with 141 rules and .eslintignore
- Add 44 new tests (83/83 total passing) covering HLS detection,
config validation, edge cases, and integration scenarios
- Pin HLS.js CDN version to 1.5.17 (not floating/latest)
- Add grid-optimized HLS config with 10s buffer cap
- Add cleanup hooks for HLS instance destruction on page unload
