feat(opencode): mandate stub-first @make pre-pass for Rust integration TDD

Rust integration tests live in a separate test crate that imports from
lib.rs, so any test referencing not-yet-existing public API can only
RED at build time. The build error masks assertion diagnostics and
makes the RED state opaque — no stack trace, no left/right values.

For Rust tasks whose @test step writes an integration test against
public API that does not yet exist, the orchestrator now dispatches a
stub-first @make pass before @test runs:

1. @make adds the planned public API as todo!()-bodied stubs in
   lib.rs and any new src/<module>.rs. Signatures lifted verbatim
   from the Phase 5 task spec. Acceptance criterion is cargo check
   only — no test command runs.
2. @test writes the integration test, which now compiles and panics
   at todo!() with a stack trace — a clean MISSING_BEHAVIOR RED.
3. Phase 7 dispatches @make again to replace the todo!() bodies with
   real implementations. Two atomic commits per task: scaffold then
   implement.

Phase 5's Rust test-path guidance now flags the two-dispatch
requirement up front. test.md's Rust failure-classification hints
recognize todo!() / unimplemented!() panics as MISSING_BEHAVIOR with
a pointer to the workflow's stub-first section.

@ -200,6 +200,7 @@ After running tests, classify each failure:
**Mapping hints (Rust):**
- `error[E0432]: unresolved import` / `error[E0425]: cannot find function/value` for the symbol under test → `MISSING_BEHAVIOR`
- `error[E0599]: no method named ...` on a real but incomplete type → `MISSING_BEHAVIOR`
- Test panics with `not yet implemented` / `not implemented: …` (from `todo!()` or `unimplemented!()` in a stub body) → `MISSING_BEHAVIOR` (this is the expected RED state for stub-first integration TDD; see workflow Phase 6 "Rust integration TDD: stub-first")
- Test panics with `assertion failed: ... left: ..., right: ...``ASSERTION_MISMATCH`
- Test file fails to compile due to its own bug (typo, wrong type, unused-import-as-error) → `TEST_BROKEN`
- `linker not found`, missing system library, missing feature flag → `ENV_BROKEN`
