Add tests/golden.rs with insta-backed snapshot assertions for:
- researcher (minimal — 3 obligatory blocks only)
- cost-guardian (minimal + output_extra_fields)
- patent-compliance (minimal + references.extra)
- code-implementer (obligatory + 4 implementer-specific blocks)
Coverage: all four frontmatter fields (name/description/tools/model),
role body, block concatenation order, domain_in / forbidden_domain /
handoffs / output format (including extra fields) / references (both
optional memory_project + project_claudemd and references.extra).
The snapshots in tests/snapshots/*.snap are the signed contract —
any change to assembler.rs output must be reviewed via
`cargo insta review` and committed alongside the code change.

- Add insta + tempfile to _assembler/Cargo.toml [dev-dependencies].
- Create tests/common/mod.rs with helpers: seed_tempdir (copies
fixtures into an isolated AGENT_ROOT), run_assemble (invokes the
built binary via std::process::Command), and assemble_one
(end-to-end single-manifest helper).
- Seed tests/fixtures/ with the 4 manifests covered by the golden
snapshots (code-implementer, researcher, cost-guardian,
patent-compliance) and the 7 blocks they reference (baseline,
evidence-grading, memory-protocol, rule-pre-dev-gate,
rule-test-first, rule-error-budget, rule-double-audit).
Binary-only crate (no lib target), so integration tests invoke the
assemble binary in-process instead of calling internal functions.
This exercises the full main.rs I/O + validator + assembler pipeline
end-to-end, which is exactly what the determinism claim covers.
