fix: treat cancelled CI runs as non-failing

[NiveditJain]

Summary

• Cancelled workflow runs (e.g. from superseded dependabot merges) were counted as failures by require-ci-green-before-stop, blocking the Stop event on branches with otherwise clean CI
• Added cancelled to the list of non-failing conclusions alongside success and skipped
• Fixed bot detection in review-policies.mjs convention hook: uses GraphQL __typename === "Bot" instead of checking for [bot] in login (CodeRabbit's login is coderabbitai, no suffix)
• Stamped CHANGELOG for 0.0.6-beta.2 release (consolidates feat: add prefer-package-manager builtin policy #126 features/docs + this fix)

Test plan

• Updated existing unit test to expect allow for cancelled runs
• All 960 unit tests pass
• All 207 E2E tests pass
