v1.0.0 — first public release

First public release of the spec-driven factory template. Highlights: full F0–F9 lifecycle with six permission-backed human gates; structured clarification, cross-artifact consistency and code↔spec convergence; derived as-is map, DORA metrics and bilingual architecture docs (sealed, CI-checked); a real, recorded demo (ADK + Gemini customer assistant) with human-in-the-loop approval; 99 TDD-first asserts across three self-test suites. Commands are English; each workspace picks its working language (en/es) at init. See CHANGELOG.md for the full list.
