feat(impact): cross-language blast-radius coverage (22 languages + 14 frameworks) (#708)

Browse Source 
Completes the cross-file dependency graph behind impact / affected / explore across all 22 supported languages and 14 web frameworks, validated on real-world repos (measured fair-coverage table added to the README). Per-language resolution + framework resolvers/synthesizers (Lua/Luau require, Shopify OS 2.0 Liquid sections, Delphi forms, Rust cross-module + Rocket macros, Swift Fluent, SvelteKit/Nuxt loader/component conventions, RN/Expo bridges). 0 cross-family false edges, full suite green (1187 passed). See #708.

## Measured cross-file coverage
Impact and blast-radius queries are only as good as the dependency graph behind them, so coverage is measured rather than asserted. **Fair coverage** = the share of symbol-bearing source files that have at least one *resolved cross-file dependent* — something that imports, calls, references, or (through a framework convention) routes to them — on a real-world benchmark repo per language. The residual is always a genuine static-analysis frontier (runtime dynamic dispatch, reflection / DI containers, framework-convention entry points, vendored third-party code), never hidden by gaming the denominator.

Framework routing is validated the same way, on a canonical app per framework: Express 100%, FastAPI 98%, Flask 100%, NestJS 96.8%, Gin 96.5%, Axum 100%, Rocket 93.8%, Vapor 100%, Laravel 92%, Rails 89.6%, React Router 100% — and the convention/reflection-heavy ones at their honest static-analysis ceiling: ASP.NET 83.9%, Spring 83.3%, Drupal 78.9%, Django 74.1%.
## Troubleshooting
**"CodeGraph not initialized"** — Run `codegraph init` in your project directory first.
