chore: migrate husky v4 to v9, switch changelog to changelog-git

- Replace husky-v4 (yarn-based) with husky v9 (.husky/pre-commit)
- Remove old husky config from package.json
- Switch from @changesets/changelog-github to @changesets/changelog-git
  (commit links only, no author thank-you messages)
