Two bugs prevented built-in LLM actors from working with models that lack a '/'
separator (e.g. claude-sonnet-4-20250514):

1. _generate_builtin_actor_yaml (actor/registry.py) was constructing the model
   field as '{provider}/{model}' (e.g. 'anthropic/claude-sonnet-4-20250514').
   The Anthropic API expects just the bare model ID, causing 404 errors. Fixed
   by using the bare model identifier and lowercasing the provider field to
   match ProviderType enum values.

2. _build_from_v3 (reactive/config_parser.py) always inferred the provider from
   the model string via infer_provider_from_model(). For models without a '/'
   separator this returned 'custom', an invalid ProviderType, causing
   'Unknown provider type: custom' at runtime. Fixed by checking for an
   explicit top-level 'provider' field in the v3 YAML data (per spec resolution
   order step 2) before falling back to inference.

As a side effect, these fixes also resolve issue #10861: agents actor run now
successfully invokes the LLM when using built-in actors. The @tdd_expected_fail
tag has been removed from features/tdd_actor_run_response.feature accordingly.

New BDD scenarios added to features/builtin_actor_v3_yaml.feature and
features/actor_v3_route_synthesis.feature validate both fixes and the fallback
inference behaviour for models with '/' separators.

All quality gates pass: lint, typecheck, 671 feature files (15673 scenarios),
1997 Robot integration tests, coverage 97.12%.
