feat: grouped PanelSwitcher, SeamEngine drift detection, quality fixes

- PanelSwitcher redesigned with grouped slide-out navigation by clade kind
- SeamEngine: drift indicators, remediation suggestions, TypeLL 41/41 resolved
- Fleet commands: validate JSON responses, fallback to offline bot list
- Valence Shell: fix TOCTOU race in test cleanup, hold lock during dir ops
- TauriEvents: subscription cleanup and consolidation
- Tea_Render: rendering improvements
- octad references in boj_engine_test and ServiceEndpoints
