feat: implement time-travel debugging and CSI replay
This commit implements the replay feature that allows users to pause the live 3D view, scrub through a 48-hour recording buffer, and replay the 3D scene exactly as it was at any historical moment. Key components: - Recording buffer with SeekToTimestamp for time-travel navigation - Replay engine with session management (start, stop, seek, play, pause) - Replay signal processing pipeline with tunable parameters - REST API endpoints for replay control - Dashboard UI with timeline scrubber, playback controls, and tuning panel - Comprehensive test coverage for all replay functionality Acceptance criteria met: - Seek to any point in 48-hour window completes in < 1 second - Replay produces identical blob positions to original live processing - Parameter sliders re-process in < 3 seconds - "Apply to Live" correctly writes parameter changes - Timeline scrubber event markers correctly align - "Back to Live" correctly resumes live detection Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
