Subject: [PATCH] perf(compose): optimize UI recompositions and state caching

- Mark ChatWorkspaceState, AgentGatewayConfig, ChatMessage, and OnboardingStep as @Immutable to enable skippable recompositions.
- Cache endpoint URL calculations in ConfigPanel using remember.
- Add performance journal in .agents/journal/bolt-journal.md.
- Add comments explaining performance optimizations.
