Introduces Synchronization Clocks — shared, controllable time bases that CSS sources can optionally reference for synchronized animation. Backend: - New SyncClock dataclass, JSON store, Pydantic schemas, REST API - Runtime clock with thread-safe pause/resume/reset and speed control - Ref-counted runtime pool with eager creation for API control - clock_id field on all ColorStripSource types - Stream integration: clock time/speed replaces source-local values - Paused clock skips rendering (saves CPU + stops frame pushes) - Included in backup/restore via STORE_MAP Frontend: - Sync Clocks tab in Streams section with cards and controls - Clock dropdown in CSS editor (hidden speed slider when clock set) - Clock crosslink badge on CSS source cards (replaces speed badge) - Targets tab uses DataCache for picture/audio sources and sync clocks Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

"""Synchronization clock data model.

A SyncClock provides a shared, controllable time base for animation-based
|

color strip sources. Multiple CSS sources referencing the same clock
|

animate in sync and share speed / pause / resume / reset controls.
