447e57ec41 fix(ai): tier-configured models reach the recipe allowlist — refresh Anthropic models, register tier resolutions, honest probe labels (#2800)
Setting `models.tier.deep anthropic:claude-opus-4-8` silently disabled
think and auto_think: the Anthropic recipe's chat allowlist stopped at
Opus 4.7, the tier-resolved model never joined the extended set that
assertTouchpoint's contract promises for config-chosen models, and the
resulting probe failure was stamped NO_ANTHROPIC_API_KEY — sending the
operator to debug env/keychain when the fix was the model id. Three
fixes, one per layer:

- recipes/anthropic.ts: add claude-fable-5, claude-opus-4-8, and
  claude-sonnet-5 to chat models; claude-sonnet-5 to expansion models.
- gateway.ts reconfigureGatewayWithEngine: resolve all four tiers and
  register the results as extended models, honoring the documented
  contract for models.default / models.tier.* (model-resolver.ts
  docstring). A tier-only model now validates like a chat/expansion one.
- think/index.ts: when the gateway client can't be built, re-probe and
  label honestly — MODEL_NOT_USABLE:<reason> for unknown_model /
  unknown_provider, NO_ANTHROPIC_API_KEY only for the actual missing-key
  case; the stub answer carries the probe detail and fix hint.

Tests: recipe-list presence pins; a new gateway-tier-extended-models
suite proving a fictional tier model validates post-reconfigure (and an
unconfigured one still doesn't); think-pipeline coverage for the honest
label (unknown_model beats missing-key even keyless); the existing
non-explicit bogus-provider test updated from the old catch-all label to
the honest one (no-throw contract unchanged).

Verified live: a brain with tier.deep=claude-opus-4-8 had think degrade
to gather-only with the misleading key warning; with this change the
probe passes and synthesis runs.
