fix: use comment.body for noop detection and set per_page: 100

[kitsuyui]

Summary

Two related issues in getManagedComment (src/github.ts):

1. Wrong field for noop detection — getManagedComment stored
   comment.body_text in the returned Comment.body, but
   createLuckyCommentAction compares pastComment.body against the
   full Markdown string (which includes the <!-- happy-commit -->
   HTML comment marker). body_text is the plain-text rendering with
   HTML comments stripped, so this comparison never matched and the
   noop branch was unreachable. Fix: use comment.body instead.

2. Missing per_page on listComments — octokit.issues.listComments
   was called without per_page, defaulting to 30 items. On PRs with
   more than 30 comments the managed comment could be missed, causing a
   duplicate to be created. Fix: add per_page: 100.

Changes

• src/github.ts: comment.body_text || '' → comment.body || ''
• src/github.ts: add per_page: 100 to listComments
• src/github.spec.ts: update listComments expectation to include per_page: 100

Verification

• All 40 tests pass (bun run test)
• Lint clean (bun run lint)
• Build succeeds (bun run build)
• madge: No circular dependencies found

Trade-offs

per_page: 100 covers most real-world PRs. Full pagination (octokit.paginate)
would handle the extreme edge case of 100+ comments but adds complexity; it can
be addressed separately if needed.
