Unify archived Flash game URL routing

[astrovm]

Summary

• replace host-wide Flash URL spoofing with one shared exact-route implementation
• make the main shell and standalone capture launcher consume the same game registry and router
• refresh Kass Basher and The Simpsons Movie: Wrecking Ball from their current Flashpoint GameZIPs
• preserve archived host/path layouts and validate every configured route against a committed file
• add behavioral router coverage and deployment hashing for the new shared script

Why

The previous interceptor flattened every request from a configured host to a local basename. That could rewrite unrelated score or tracking requests, collide on duplicate filenames, and silently target missing files. The capture launcher also maintained a separate copy of host and frame-rate data, which had already drifted from the main application. The bundled Simpsons and Kass Basher files were incomplete or stale compared with Flashpoint.

Exact URL-to-file routes keep the sitelock-compatible response URL behavior while only intercepting assets that actually exist.

User impact

Sugar, Sugar; Kass Basher; and The Simpsons Movie: Wrecking Ball now use deterministic archived asset routes. Simpsons gains its missing score and sound dependencies, Kass Basher uses the current Flashpoint package, and offline manifests include the complete imported content trees.

Validation

• bun run quality
• bun run test — 124 tests passed
• bun run build --revision HEAD
• all eight configured routed assets returned HTTP 200 from the local development server

Browser GUI smoke testing was not completed because the in-app browser could not navigate to localhost; router behavior and served assets are covered independently.
