Same suppression as in fai/platform's modules/echo: wit_bindgen
0.36's export! macro expands into unsafe fns whose bodies call
further unsafe fns without explicit unsafe blocks, and Rust 2024
makes that an error under -D warnings. Drop once wit_bindgen
ships a fix.
Gated on target_arch wasm32 so the host build (tests, plan
validation) stays strict.

The orchestrator now calls a configured Ollama-compatible LLM
endpoint over wasi-http and emits the LLM-generated plan back
to the hub. When llm_endpoint is empty, the v0.1.0 deterministic
stub is preserved as fallback (useful for tests and air-gapped
environments).
- module.yaml: bump to 0.2.0; new inputs llm_endpoint,
llm_model, llm_api_key; net: permissions for OpenAI,
Anthropic, localhost, 127.0.0.1 (Ollama defaults)
- src/llm.rs: LlmClient trait, OllamaParams, build_user_prompt,
build_ollama_body, extract_ollama_content, generate_plan;
9 unit tests for prompt-building and response-parsing
- src/plan.rs: tagged enum with Explain/SaveFlow/RunFlow/
InstallModule variants; parse_and_validate; build_stub_plan
(renamed from build_plan); validate(); 6 unit tests
- src/lib.rs: WakiClient implementing LlmClient over the waki
WASI-0.2 HTTP crate (wasm32-only); empty endpoint → stub
- Cargo.toml: 0.2.0; thiserror dep; waki dep gated on wasm32
17 host-side tests pass. WASM bundle is 386KB (was 74KB; the
delta is wasi-http via waki, expected). The deny path is
exercised by the platform-side integration test in
fai_platform/crates/fai_hub/tests/orchestrator_llm_path.rs.

The orchestrator-llm module turns a goal text into a Plan JSON
that the F∆I hub can apply. v0.1.0 is a deterministic stub —
it always emits a three-step plan (explain, explain-stub-notice,
save_flow with debug.echo) regardless of the goal.
Why ship a stub: it validates the module → plan → apply pipeline
end-to-end before adding LLM integration. The output is a
structurally valid Plan that round-trips cleanly through
fai_hub::plan::Plan deserialization.
v0.2.0 will replace the stub body with an actual LLM call once
the F∆I platform exposes outbound HTTP to permitted modules via
wasi-http.
