fix: use 'build' type instead of 'chore' in release script

The new commit-msg hook only allows specific commit types (feat, fix, docs,
style, refactor, perf, test, build, ci). Changed release script to use 'build'
type which is appropriate for version bumps and releases.

- Changed commit message from 'chore:' to 'build:'
- Changed PR title from 'chore:' to 'build:'
