Parfii-bot e3053df706 test(assembler): add insta dev-dep and fixture-loading helpers

- 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.

TEST-FIRST

Critical paths: tests BEFORE code (TDD — RED → GREEN → REFACTOR)
Everything else: tests WITH code in the same change
NEVER "I'll write tests later"

Goal-Driven variant: convert any task to a verify-criterion BEFORE starting.

"Add validation" → "Write tests for invalid inputs, then make them pass"
"Fix the bug" → "Write a test that reproduces it, then make it pass"
"Refactor X" → "Ensure tests pass before and after"

Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.
