opencode / the ai-sdk OpenAI-compatible client sends a large default max_tokens
(> the server's --max-tokens cap, 1024 by default), and generation_options
returned 400 "must be an integer between 1 and 1024" — even for a trivial
"hello". OpenAI-compatible servers clamp to their own ceiling rather than
reject. Now max_tokens > limit is clamped to limit; only non-int / non-positive
values are a hard error. Test updated to assert the clamp + keep the <1 reject.

Two OpenAI-compat tool-calling bugs found against the real GLM-5.2 (dnnspaul): (1) string-typed args coerced to numbers — declared schema type now decides, string kept verbatim, bool rejected as number, schema-less params keep permissive decoding; (2) tool_choice was ignored — none/auto/required/{function} now honored, invalid returns 400. Python-only (openai_server.py + tests), engine untouched. 36/36 tests pass (verified independently in a clean worktree).
