[joshuawheelock]

[3.6.1] - 2026-06-06

Changed

• Internal: Decomposed Cockpit screen into focused collaborators (AnimatedBannerColorGradient, AnimatedBannerLineColorSegments, AnimatedBannerTiming, CockpitDaemonAgentConfigCycler, CockpitDaemonConfigsUpdater, CockpitDaemonEventSnapshot) for improved testability and separation of concerns.
• Internal: Replaced 62 as-any casts in ProjectionBusFactory with type-safe event dispatch, eliminating unsafe type coercions across the projection bus.

Fixed

• CI gate: Added PR gate workflow for lint, type-check, and build validation on pull requests.
• Lint errors: Resolved all ESLint errors introduced during TUI decomposition.
• Test stability: Fixed flaky tests and added missing test coverage for daemon panel status labels, codifier daemon constants, and CenteredPrompt.
