Introduce a reusable Warning { kind, message, details } variant in
AgentEvent so non-fatal warnings (context window usage, deprecation,
etc.) share a single event shape. The context_window warning preserves
all original fields inside the JSON details object.

Replaces set_subagent_manager() with an Option parameter on the

Move model facts (knowledge_cutoff, context_window) to fabro-model catalog as
source of truth. Move request-shaping (auto-thinking, 1M beta headers, Gemini
safety settings) into fabro-llm adapters. Delete ProfileCapabilities struct and
all dead code (supports_reasoning, supports_streaming, supports_parallel_tool_calls,
OpenAiProfile.reasoning_effort). Fix "powered by OpenAI" mislabeling for
Kimi/ZAI/Minimax/Inception providers.
