sususu a2933c7737 fix(claude): scope Anthropic beta and count_tokens policies ...

Claude Code builds Anthropic-Beta per request instead of sending a fixed list.
Captured from an isolated 2.1.220 profile pointed at api.anthropic.com through
a local proxy, over two rounds covering 11 model IDs and the [1m] variants:

  constant  claude-code, interleaved-thinking, redact-thinking,
            thinking-token-count, context-management, prompt-caching-scope
  tools     advanced-tool-use-2025-11-20 only when tools are declared
  model     mid-conversation-system-2026-04-07 only on models that accept a
            role=system turn
  [1m]      context-1m-2025-08-07, directly after claude-code-20250219 rather
            than at the end
  trailing  effort-2025-11-24, then server-side-fallback-2026-06-01

claude-sonnet-5 emits mid-conversation-system-2026-04-07, so it accepts a
role=system turn and must not sit in the legacy reminder whitelist.

count_tokens does not reuse the inference fingerprint. Running /context in an
interactive session issues 37 identical calls, which made the endpoint
observable for the first time: four betas only, and 21 headers rather than 22
because X-Stainless-Timeout is absent. The profile is selected from the request
path so no call site has to thread another flag.
