Greptile Summary

This PR adds the new Overwatch package for running repository repair loops. The main changes are:

• Daytona-backed sandbox provisioning and repository access.
• Sensors, pickers, coding-agent actuators, and retry verification.
• GitHub PR creation, claim tracking, and review-comment handling.
• A CLI, package build, publishing workflow, tests, documentation, and examples.

Confidence Score: 4/5

Concurrent execution and partial GitHub operations can create duplicate PRs or lose comment updates.

• The open-PR limit is not atomic across overlapping runs.
• Comment updates to the same branch can race and discard one invocation's work.
• Failed label application hides an existing PR and its claims from later runs.
• Claim parsing and review-thread pagination can reprocess completed work.

overwatch/src/control-loop.ts, overwatch/src/github.ts, overwatch/src/claims.ts, overwatch/src/actuators/agent-pr.ts

Important Files Changed

Filename	Overview
overwatch/src/control-loop.ts	Adds the main run and comment-application state machines; concurrent runs can exceed the PR cap or lose comment updates, and feedback is duplicated in the current prompt.
overwatch/src/github.ts	Adds GitHub cloning, PR, label, comment, and push operations; partial PR creation loses claim visibility and resolved-thread lookup is truncated.
overwatch/src/claims.ts	Adds PR-body claim markers whose delimiter-based format can be broken by valid signal text.
overwatch/src/actuators/agent-pr.ts	Adds iterative agent repair and PR creation, with an uncompensated pushed-branch state when PR creation fails.
overwatch/src/agents.ts	Adds Claude and Codex adapters with staged prompts and sandbox command execution.
overwatch/src/sensors/ast-grep.ts	Adds scoped ast-grep execution and conversion of matches into signals.
overwatch/src/sensors/react-doctor.ts	Adds react-doctor execution and conversion of diagnostics into signals.
overwatch/build.ts	Adds per-file CommonJS compilation with esbuild.
overwatch/package.json	Defines package entry points, scripts, dependencies, engines, and publishing settings.
