fix(changelog): find original author of agentic commits

fix(changelog): make co-authors first-class authors; keep all contributors

Addresses the Copilot review on PR #39:

- Co-authors overwrite (utils.js): instead of storing co-authors in a
  per-author field that a later commit could overwrite, every
  `Co-authored-by` trailer now becomes a first-class entry in the authors
  map (keyed by login). This drops co-authors no more, regardless of how
  many commits an author has, and works whether or not Slack IDs are
  fetched. getCommitCoauthors now returns { login, name, email }.

- getAuthorsWithSlackIds no longer drops contributors. Restored to the
  documented contract (action.yml / PR description): return every author
  and attach `slackId` only when it can be resolved, rather than filtering
  out anyone without an org email or Slack match.

Rebuilt dist.

feat(changelog): exclude bots and ignored logins from authors

Adds bot/author filtering so release notifications don't tag automation
accounts (Copilot, Claude) while still crediting the real humans behind
their commits:

- Commit authors with GitHub account type "Bot" are always skipped.
- New `ignore-authors` input (comma-separated logins, default
  "Copilot,Claude", matched case-insensitively) excludes both commit
  authors and `Co-authored-by` trailers. A bot commit's real co-authors
  are still kept.

Rebuilt dist.
