Release v0.7.0 — repo AI-usage scanner + Action, example gallery, refreshed demo · JKasteele/ai-act-companion

A distribution release: makes the project easy to see and to adopt.

Added

Repository AI-usage scanner (ai-act scan) + a reusable GitHub Action (action.yml) — flags whether a codebase appears to use AI/ML (dependency manifests, source imports, model artifacts) and points to the EU AI Act questions worth asking (Art. 2/5/6/10/50). Deterministic, stdlib-only, no model calls — a relevance flag, not a classification. Writes a Markdown PR/job summary; --fail-on-detect turns it into a gate.

```
Static example report gallery (docs/examples/) — real generated artifacts for the synthetic examples (risk, AI-security, STRIDE, red-team, controls, data-security, FRIA, …), viewable on GitHub without running anything.
Demo inventory seeding — in DEMO_MODE the synthetic examples are pre-loaded, so the inventory and the portfolio roll-up are populated on a fresh ephemeral Space instead of empty.

116 tests pass; ruff + bandit clean.
