fix(hooks): check only new commits in pre-push, not all since release

The pre-push hook was checking all commits since the last release tag
(v0.1.2), which included 4914 commits. This blocked pushes even when
problematic commits were already on remote.

Changed existing branch logic from:
  range="$latest_release..$local_sha"  # All commits since v0.1.2

To:
  range="$remote_sha..$local_sha"  # Only new commits being pushed

This prevents blocking pushes for old commits that already made it to
remote, while still catching new commits with AI attribution.
