Jason bdc4c1e8b8 fix(proxy): derive Claude auth strategy from ANTHROPIC env var name
Anthropic SDK assigns distinct semantics to the two env vars:

- ANTHROPIC_API_KEY    -> x-api-key
- ANTHROPIC_AUTH_TOKEN -> Authorization: Bearer

The Claude adapter previously collapsed both into AuthStrategy::Anthropic
and then emitted Authorization: Bearer regardless, breaking strict
Anthropic-protocol endpoints (Anthropic official, Cloudflare AI Gateway,
OpenCode Go, DashScope) and silently overriding the user's intended auth
scheme.

- claude::extract_auth: infer strategy from env var name
  (ANTHROPIC_AUTH_TOKEN -> ClaudeAuth, ANTHROPIC_API_KEY -> Anthropic),
  matching the precedence already used by extract_key.
- claude::get_auth_headers: split the Anthropic arm so it emits
  x-api-key, while ClaudeAuth and Bearer continue to use Bearer.
- stream_check: reuse ClaudeAdapter::get_auth_headers as the single
  source of truth, replacing the prior "always Bearer + maybe x-api-key"
  double injection that produced auth conflicts and false-negative
  health checks.
- Cover each strategy -> header mapping and env-var precedence with
  new unit tests in claude.rs.
