v0.21.0

• codex works in worktrees: its agents can report their task done or blocked again. The sandbox now grants the directory holding orch.db, where it used to answer "readonly database" (#387). A route's effort reaches codex too (#388), and cached input counts in the budget like other providers' (#389).
• Committed work is never thrown away: a retry keeps an earlier attempt's unpushed commits under orch/<id>-salvage-… instead of deleting the branch, and orch task salvage --id X --accept <branch> takes them as the task's result without running the agent again (#391).
• A retry whose branch already has an open PR reuses that PR instead of blocking with "no PR was opened" (#386).
• The task page: details and activity split 70/30 with a resizable handle, and comments read as a thread instead of raw JSON (#404, #405). report_findings is on again in new projects (#399).
