feat: add llmman as an OpenAI-compatible provider

[ericcurtin]

Closes #7216

Adds llmman, which runs local models distributed as OCI artifacts and serves an OpenAI-compatible API on port 17434.

• Provider config. No API key, so it follows the Ollama entry (api_key_required=False, a default_api_key) rather than the hosted ones. LLMMAN_HOST is a bare host:port value, so it joins the /v1 base-URL normalization. That helper is renamed _normalize_local_base_url now that it serves two providers.
• Runtime routing. Registered in SUPPORTED_NATIVE_PROVIDERS, the model-prefix map and _get_native_provider, so both llmman/qwen3.8 and LLM(model="qwen3.8", provider="llmman") reach OpenAICompatibleCompletion instead of falling back to LiteLLM.
• CLI. Added to PROVIDERS, ENV_VARS and MODELS, using bare model names since llmman resolves those to OCI artifacts itself.

Testing

$ pytest lib/crewai/tests/llms/openai_compatible/
40 passed

The existing 35 plus 5 new: registry config, base-URL collision, LLMMAN_HOST normalization, and factory routing for both the prefixed and explicit-provider forms. The wider lib/crewai/tests/llms/ suite shows the same 306 pre-existing failures before and after this branch.

Not verified: no request against a live llmman server.

Changes

llmman provider integration

Layer / File(s)	Summary
Register llmman provider support lib/cli/src/crewai_cli/constants.py, lib/crewai/src/crewai/llms/providers/openai_compatible/completion.py	Adds llmman defaults, provider metadata, supported models, documentation, and /v1 URL normalization.
Validate llmman configuration lib/crewai/tests/llms/openai_compatible/test_openai_compatible.py	Tests the llmman registry configuration and verifies that its default port does not collide with another provider.

Merge Risk: 🟡 Moderate · up to 34524

The PR exposes llmman through CLI configuration, but runtime dispatch does not currently recognize the provider, so selected models may bypass the intended local OpenAI-compatible endpoint and fail or use incorrect routing. Merge should wait for the runtime mapping and regression coverage to be added.

Register llmman in runtime provider dispatch.

The provider configuration defines llmman, but the runtime factory and native-provider allowlist do not route it to OpenAICompatibleCompletion. Explicit LLM(..., provider="llmman") and CLI-generated llmman/... models can therefore fall back to LiteLLM or fail, bypassing llmman's intended endpoint normalization and authentication behavior.

Add llmman to the model-prefix and native-provider mappings, and add factory regression coverage for both explicit provider selection and llmman/... model names.

GitHub refuses to reopen this one (state cannot be changed. The feat/llmman-provider branch was force-pushed or recreated), so I have continued in #7217, which links the tracking issue #7216 as the bot requested. That PR also fixes the CodeRabbit finding here: llmman is now registered in the runtime dispatch in llm.py, not just the provider registry.
