🐛 fix: match identical bypass comments consistently

[SigureMo]

When someone outside the CI team posts /bypass ci before a CI member posts the same command, the shared global regex retains lastIndex and can skip the authorized comment. Compile comment patterns without the g flag so each comment is matched independently, and rebuild dist/index.js.

Validation:

• vp test: all 31 existing tests passed.
• vp check: formatting, lint, and type checks passed.
• vp pack: bundled JavaScript rebuilt successfully.
• Executed the original and rebuilt bundles against a local mock GitHub API. The outsider-then-member sequence changes from incorrectly rejecting the bypass to accepting it; member-first, outsider-only, and member-only controls retain their expected results.
