feat: add ollama/qwen3.5-9b-q4_k_m model params

[zunami]

Adds parameter definitions for qwen3.5:9b-q4_K_M running via Ollama.

Intentionally omits thinking.type — Ollama reports capabilities: ["thinking"]
via /api/show, but does not accept the Anthropic-style thinking API parameter.
Sending it causes "Failed to reach upstream provider" errors.

Ollama handles thinking internally via prompt prefix (/no_think), not via
API parameters.

Thanks for the contribution, @zunami — and sorry for the slow look! 🙏 A few things to sort before this can go in:

1. Provider should be the maker, not the runtime. The catalog is keyed by who makes the model, not how it's served — so Ollama-served models live under their maker. Qwen is Alibaba, and we already track it at models/alibaba/ (qwen3.5.yaml, qwen3.5-flash.yaml, …). A new top-level ollama provider would be the first gateway/runtime in the tree, which we've been avoiding (same reason OpenRouter/OpenCode-Go aren't providers here).

2. Param surface. The file mixes OpenAI-compatible params (max_tokens, top_p) with Ollama-native ones (num_ctx, top_k). Worth picking one surface — and note Ollama's own max-output option is num_predict, not max_tokens. Also missing the schema header the other files use:

# yaml-language-server: $schema=https://modelparams.dev/api/v1/schema.json

3. CI is red + branch is stale. It needs a rebase on main, and the generated package files have to be regenerated and committed (npm run codegen --workspace=modelparams) or the "generated files in sync" build fails.

One open question worth your thoughts: since alibaba/qwen3.5 already exists, is a separate entry for the local quantized :9b-q4_K_M tag adding configurable params that the existing entry doesn't cover? If the knobs are the same, it might be redundant; if the quant exposes genuinely different Ollama options, that's the case to make. Happy to help reshape it whichever way you'd like to take it. 🙂
