jinzhenjandClaude Code dd20bf0052 refactor(parser): drop dead backend_for_tier chain and Hybrid-era locks
- Remove backend_for_tier / CANONICAL_HYBRID_ENGINE and the backend
  field from ParserRuntimeOptions: the string had no runtime consumer
  (doc_analyze takes effort + vlm_config, not a backend name) and
  returned the retired hybrid-engine value
- Drop the write-only application.state.backend storage
- Flip the as_kwargs/state.backend assertions to effort-based ones and
  remove the locked hybrid-backend mapping test
- Point the PARSER_BACKENDS changelog note at model.small_backend and
  model.vlm.engine instead of the removed helper
