feat(python/robomp): added the wontfix primary classification and comment-only triage path

- Added `wontfix` to primary classification handling by updating host-tool classification metadata and issue taxonomy prompts.
- Updated kickoff/follow-up/system prompt guidance to treat intentional-design reports as `wontfix`, with maintainer-intent signals stopping work and ending in a single explanatory comment.
- Added tests to verify `classify_issue` persists a `wontfix` classification and returns a no-PR, comment-only next step.
