What changed in v0.3.0:

Cross-Language Execution: real code in any language via subprocess + stdin/arg. Config: .specify/golden-demo/config.json
Deterministic Fuzzing (seed=42): edge-case vectors auto-generated (empty, null, negative, maxsize, unicode, 1000+ items). SHA-256 verified across 2 independent runs.
Auto-Golden Generator: new speckit.auto-golden command, Gemini-first LLM, human [y/N] approval required, CI-safe (writes suggestions.md only without --auto-approve)
CI/CD Gatekeeper: GOLDEN_DEMO_MODE=warn (exit 0) or strict (exit 1 on drift)
Commands: 3 (was 2, added speckit.auto-golden)

Testing: fuzzing determinism verified via SHA-256, non-interactive safety 3/3 checks passed, Node.js cross-language E2E test passed.
