Codebase Argus v0.2.0: a shorter first review and a GitHub Action

[AaronZ345]

Codebase Argus v0.2.0 is now live with a shorter path from clone to first useful review.

The release focuses on three maintainer jobs: reviewing a pull request, diagnosing failing GitHub Actions, and checking whether a long-lived fork can safely sync. The dashboard and README now lead with those workflows instead of the setup details.

A few concrete pieces to try:

• Live demo
• CowAgent #2965 case study, with deterministic and Codex CLI passes
• Codebase Argus Action, which puts a read-only report in the job summary
• v0.2.0 release notes

The default review needs no model key. Agent-backed reviews receive the same evidence package, and provider failures remain visible in the report.

I would especially value feedback from maintainers on two questions: does the report contain enough evidence to verify a finding quickly, and which missing signal would most improve a real PR decision?
