Integrate transpiled Functions filter with selfhost tests
- Add _setup function to transpiled filters for binding module-level functions- Update FilterProcessor to call _setup on filters that support it- Load Functions filter automatically when running functions_spec- Add s()/S() node creation helpers with is_method() supportfunctions_spec now runs with the transpiled Functions filter:- Previously: 16 passed (base converter only, no filter)- Now: 70 passed (with transpiled Functions filter)🤖 Generated with [Claude Code](https://claude.com/claude-code)Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
