fix(openrouter): never send reasoning field for adaptive Anthropic models (#43012)
The previous fix (#42991) only omitted reasoning when it was being disabled.
But reasoning-mandatory Anthropic models (Claude 4.6+, fable) 400 with
thinking.type.disabled on EVERY tool-continuation turn even when reasoning is
enabled: chat_completions never replays signed thinking blocks, so the prior
assistant tool_call has no thinking, and OpenRouter resolves "reasoning
requested but history has none" by emitting thinking.type.disabled — which
these models reject. Result: first turn works, every turn after the first tool
call dies (HTTP 400, non-retryable).

OpenRouter ignores reasoning.effort for adaptive Anthropic models anyway (the
model self-decides), so the reasoning field is pointless for them on every turn
and harmful on tool-replay turns. Omit it entirely → adaptive default.

- openrouter profile: drop the reasoning field for reasoning-mandatory Anthropic
  models regardless of enabled/disabled; legacy Anthropic + non-Anthropic models
  unchanged.
- tests: assert omission across enabled/disabled/effort variants; parity tests
  switched to a non-Anthropic reasoning model (deepseek) since Anthropic 4.6+ no
  longer carries a reasoning field.

Verified live end-to-end: a tool-replay turn on anthropic/claude-fable-5 with
reasoning enabled now builds extra_body=None and returns HTTP 200 (was 400).
