fix(skills): treat internal-scope feat commits as patch in /release (#642)

* fix(skills): treat internal-scope feat commits as patch in /release

The release skill's auto-detect logic treated any feat: commit as a
minor bump. Internal dev tooling scopes (titan, skills, hooks, ci,
bench, dogfood, etc.) are not user-facing features and should not
trigger a minor version bump. Add an explicit exclusion list so these
scopes count as patch.

* fix(skills): clarify minor-bump wording, alphabetize scopes, add patch example (#642)
