wip: team messages panel updates and runtime usage cache refinements

Checkpoint of in-progress work:
- renderer: team messages panel/composer, messagesPanelLogic, teamSlice,
  AnimatedHeightReveal plus their tests
- main: runtime process usage-stats caching (ignoreCachedMisses, bounded
  eviction), alive-run-id helpers, team watch-scope notify wiring

Note: the getTeamAgentRuntimeSnapshot rssBytes expectation in
TeamAgentLaunchMatrix.safe-e2e is environment-dependent and still red.
