Updates to Agent_00, Molten Bot, molten.bot.

Expanded Git Chat with repo search and pagination, first-repo default selection, repo visibility and organization icons, stronger selected-repo states, full-width messaging, and mobile-friendly truncation.

Made chat task completion clearer with status-coloring, PR-ready replies, GitHub link treatment, green completed-task states, and social sharing actions.

Reworked Session Dashboard metrics with task mix and PR stats, themed charts, runtime duration, rounded stat formatting, relative update times, and inactive pre-task navigation.

Improved harness handling for previous task-log review, Codex plan messages, prompt fallback, and safer task-description display, with regression coverage across the app and broker paths.

Documented OpenCode support, added its logo asset, and centralized shared auth-gate behavior across Auggie, OpenCode, and PI harnesses.

Retired the local app Releases view and bottom-dock release action after PR availability moved into chat completion flows.

Added BigBrain runtime chat with websocket-backed conversation snapshots, live event merging, approval and run-state handling, usage display, and formatted assistant message rendering.

Published the May 7 release rollup without changing existing historical release entries.
