GitHub Integration: PR Agent and CI Agent (MC Prevent)

Monte Carlo's GitHub integration now includes two agentic guardrails completing the code review and merge gate stages of MC Prevent.

PR Agent automatically posts a risk assessment on every pull request, covering affected tables, downstream blast radius, and active alerts, the moment a PR is opened. Comment mc review on any PR to re-trigger an assessment.

CI Agent is an optional GitHub Action (and CircleCI orb) that converts the PR Agent's assessment into a pass, warn, or fail verdict posted as a GitHub Check Run. It ships in warn-only mode by default; switch to fail-on-high-risk to block high-risk merges via branch protection. Add mc-override to any PR to bypass the gate, with all overrides logged.

Existing GitHub integration customers need to reauthenticate to use the new features. CI Agent requires PR Agent.
