Fixes crewAIInc#7303 OpenAI's flagship reasoning models (o1, o1-pro, o3) support 200,000 context windows but were missing from crewAI's context window tables. This caused queries with these models to fall back to the default 8k window, triggering false LLMContextLengthExceededError or premature prompt truncation. Changes: - Add o1, o1-pro, o3 (200k each) to LLM_CONTEXT_WINDOW_SIZES in llm.py - Add o1, o1-pro, o3 to OpenAI provider's context_windows dict - Add o1, o1-pro, o3 to Azure provider's context_windows dict - Add parametrized test for o-series context windows Verified: - test_o_series_context_window passes for o1, o1-pro, o3 - Existing test_context_window_validation still passes

Restore the specific o1 mappings.
get_context_window_size keeps the last matching prefix. This later generic "o1" entry overrides "o1-preview" and "o1-mini". Both models resolve to 200000 instead of 128000. Move "o1" before the specific entries, or select the longest matching prefix.

Summary
Fixes #7303: OpenAI reasoning models (o1, o1-pro, o3) fall back to 8k default context window instead of their official 200k.
Root Cause
OpenAI's flagship reasoning models (
o1,o1-pro,o3) and Azure OpenAI deployments ofo1,o1-mini, ando3-miniwere missing fromLLM_CONTEXT_WINDOW_SIZESand native provider context window tables.Because prefix lookup fails (
"o1".startswith("o1-preview")is false), querying withmodel="o1"ormodel="o3"falls back toDEFAULT_CONTEXT_WINDOW_SIZE(8,192 tokens, or 6,144 usable tokens with ratio) instead of their official 200,000 tokens. This can trigger falseLLMContextLengthExceededErroror premature prompt truncation.Changes
