fix(release): support custom conventional commit types

[AI-JamesHenry]

Current Behavior

Nx Release only recognizes conventional commit types containing ASCII letters. Configured types such as ✨ are rejected, while identifiers such as 2026_A can be misparsed as a suffix.

Expected Behavior

Configured custom commit types are parsed as complete tokens, including gitmoji and identifiers containing digits or underscores. Standard scoped and breaking-change syntax continues to work, and the reported optional whitespace before a scope is supported.

Focused parser unit coverage passes for both reported formats, standard syntax, and invalid messages.

Nx Cloud has identified a flaky task in your failed CI:

Since the failure was identified as flaky, the solution is to rerun CI. Because this branch comes from a fork, it is not possible for us to push directly, but you can rerun by pushing an empty commit:

git commit --allow-empty -m "chore: trigger rerun"
git push
