chore(config): add gdlint + gdformat + cargo-deny to pre-push hook

Pre-push now runs 6 checks:
- GDScript: parse check, gdlint (static analysis), gdformat (style)
- Rust: clippy, fmt, cargo deny (license/advisory/deps)
All tools degrade gracefully if not installed.

Also files Q-065 through Q-080: shooting mechanics, procedural terrain,
cloth sim, vehicle physics, PathMesh3D, NobodyWho vs voice pipeline,
BitTorrent distribution, BehaviourToolkit patterns, screenshot manager,
RichText3D, DeformableMesh, GridMapLayer, mod loader, god rays,
Steam multiplayer, CityCrafter3D, planet generator.
