fix: resolve runtime, review, channel and chat state failures

Keep remote startup cancellable without blocking other sessions and surface local OpenCode submission failures promptly. Preserve supervisor project isolation, pause behavior and valid story destinations.

Restore generated-image channel delivery, Telegram reconnection on unchanged Save and DingTalk business-error retries. Preserve virtualized message disclosures using sparse state and release stale supervisor UI requests.

Add production-path regressions, Electron checks, isolated SQLite validation and audit evidence. Fix the SDK cleanup test fixture lifetime under garbage collection without weakening its assertions.

Validation: 6136 tests passed, 87 skipped; typecheck, lint and diff checks passed. Seven real text-model calls, current-source Linux x64 Host scenarios and large-history Electron comparisons completed.

Release note: Fix stuck runtime requests, inconsistent review results and channel delivery failures, and retain expanded details while browsing long conversations. Remote runtime fixes require an Agent build containing these changes.
