feat(routing): discover static routes across HTTP frameworks

[bompus]

CodeGraph now discovers literal HTTP routes in Hono, Elysia, Fastify, Hyper-Express, Koa router, H3, Bun, Effect v4 and option-free Vixeny builders. An imported handler in new Hono().get('/users', handler) becomes GET /users linked to that handler; inline handlers contribute their direct calls, and static responses get endpoints without invented handler links.

Nuxt's default file routes now handle root index pages, Nuxt 4 route groups, server/routes/, server method suffixes and catch-all paths. Server default exports and standard event-handler wrappers link to their handlers. Existing Next Pages/App Router and Vue navigation behavior is retained.

The reader uses the existing tree-sitter parser and follows package imports, immutable local router bindings and supported same-file prefixes/mounts. Computed paths, spread configuration, cross-file mounts, runtime mutation and plugin factories are outside coverage. Vixeny options, Nuxt custom configuration and member-handler resolution remain unsupported. Re-index existing projects after upgrading; no new dependencies or application execution.

Validation:

• Full build, including the viewer and packaged grammar checks.
• Full test suite with the matching native kernel: 4,342 passed, 46 skipped (242 suites passed, 5 skipped).
• 116 focused routing tests passed with a freshly built matching native kernel loaded.
• 36 declarations matched across six pinned official-source fixtures; Hono, Fastify, Elysia and H3 were also checked through full indexing. Bun and Effect checks cover the documented source ranges. Hyper-Express, Koa and Vixeny have synthetic indexing tests only.
• Independent review findings were fixed and rechecked; final bounded review found no blocker or obvious complexity to remove.

Start review with src/resolution/frameworks/http-routing.ts and its tests. The route guide documents supported shapes; docs/design/framework-coverage.md links the exact official fixtures and records their limits.
