- Add ServiceEnvironment.swift with 9 EnvironmentKeys for runtime services (stateStorage, lifecycle, keyEventDispatcher, renderCache, preferenceStorage, pulsePhase, cursorTimer, focusIndicatorColor, activeFocusSectionID) - Remove tuiContext, pulsePhase, cursorTimer, focusIndicatorColor, and activeFocusSectionID as direct RenderContext properties - Inject all services through EnvironmentValues in RenderLoop.buildEnvironment() - Add convenience RenderContext init that accepts TUIContext and auto-injects services into the environment - Simplify isolatedForBackground() to only swap environment values - Migrate ~49 access sites in ~25 source files from context.tuiContext.X and context.pulsePhase/cursorTimer to context.environment.X - Update 38 test files to use the new convenience init
