feat: support and test MDCPS reviewer identity per #107

- Update v2 test config: mdcps reviewer username '913443' (distinct from author 'jcwalker3'), author 'jcwalker3'
- Adjust TBD negative test to use mutate (post-provisioning)
- Add mdcps-reviewer example to gitea-mcp.example.json and README
- Verifies distinct identities, reviewer cannot create/push, author cannot review/merge

Closes #107

Checks:
- config tests pass
- no secrets in changes (usernames only)
- py_compile and diff clean
