[codex] fix issue status flow

[Chener]

Summary

• Invalidate project queries when issue membership or status changes so project progress counters refresh after manual status changes.
• Preserve derived issue/resource counters on project update responses.
• Advance assigned-agent and assigned-squad comment-triggered issues to in_progress after a task is successfully queued.

Root Cause

• Project progress was cached separately from issue status mutations and WebSocket issue updates, so a project could keep showing stale done_count / issue_count after an issue moved to done.
• Comment-triggered agent work queued a task but did not update the issue status from in_review to in_progress, leaving active AI work visually stuck in review.

Validation

• go test ./internal/handler -run 'TestCreateComment_AssignedAgentReopensReviewToInProgress|TestCreateComment_AssignedSquadReopensReviewToInProgress|TestCreateComment_MentionedAgentDoesNotChangeIssueStatus|TestProjectResourceCountBreadcrumb'
• go test ./internal/handler
• corepack pnpm --filter @multica/core exec vitest run issues/ws-updaters.test.ts
• corepack pnpm --filter @multica/core test
