no-mistakes gates git push with QA

This is a pragmatic answer to the messiest part of agentic coding: not generating code, but deciding when it is actually safe to ship. By moving review and repair ahead of the push, no-mistakes treats QA as a preflight check instead of a post-PR cleanup step.

• –The disposable worktree is the key architectural choice: it isolates validation from the developer’s live branch and reduces the chance of contaminating work in progress.
• –Pushing into a gate instead of `origin` changes behavior, not just tooling, which is how you get real process enforcement.
• –Agent-agnostic support is smart because the ecosystem is fragmented across Claude, Codex, OpenCode, and others.
• –Auto-opening clean PRs is the right UX layer for teams that want guardrails without making developers babysit every step.
• –The tradeoff is latency, but that is the point: this tool is optimizing for fewer broken pushes, not faster ones.
