v2.11.2

Trimmed the model pickers (Claude Fable 5 is de-listed — unavailable under the US export ban — and a few older variants drop off), and editor clients (VS Code, Zed) now see API retry/backoff instead of an endless "Thinking…" spinner.

Changed

• Model picker cleanup across every provider. Claude Fable 5 is removed
  from the Anthropic picker (unavailable under the US export ban; Opus 4.8 stays
  the default). Z.AI drops glm-5.1 and glm-5 (keeps glm-5.2 + glm-5-turbo);
  OpenAI drops gpt-5.4-nano (keeps 5.5 / 5.4 / 5.4-mini). DeepSeek, Google, and
  MiniMax are unchanged. All ids remain valid if set by hand — they're just no
  longer offered. Context/cost tables updated to match.

Fixed

• ACP retry visibility. When a request hit a transient API error and the
  agent retried with backoff, the ACP path dropped the notice (only the bare
  iteration counter was suppressed, but the retry message went with it) — so
  editor clients showed an indefinite "Thinking…" while the CLI was actually
  retrying. Retry/backoff notices ("API 429 … retrying in 10s (1/3)") and
  context warnings (⚠) are now forwarded as agent thoughts; the plain
  iteration counter stays internal.
