feat(routing): discover static HTTP and Nuxt routes

[bompus]

Literal routes in several JavaScript HTTP frameworks currently lack accurate endpoint and handler links. Add discovery for Hono, Elysia, Fastify, Hyper-Express, Koa routers, H3, Bun, Effect v4 and option-free Vixeny builders, including references to named handlers and calls from inline handlers. Correct Nuxt 4 default page groups and server route method suffixes.

For example, app.get('/users', listUsers) on an imported Hono instance produces a GET /users endpoint linked to listUsers. Recognition follows verified imports and supported immutable bindings; unrelated .get() calls, shadowed bindings and computed paths do not become routes. Cross-file mounts and custom Nuxt routing conventions remain unsupported.

The import-aware HTTP extractor is the main review starting point. Express duplicate suppression and Nuxt's default filename handling are included alongside the coverage documentation and regression tests. No dependencies or schema changes are introduced.

Validation on this branch, based on upstream b9ca4b7: TypeScript compilation and the full build passed; 116 tests passed across HTTP routing, Nuxt routing, Next.js and Vue Router. Validation ran on Windows with the native kernel built from upstream source. This branch's standalone full test suite has not been run; these results do not claim a green full suite or cross-platform validation.

Planned follow-up contributions

We have 13 additional routing contributions prepared in our fork and plan to submit them incrementally, rebasing and validating each for upstream review. The links below are fork PRs, not submitted upstream PRs. They provide visibility into the work available; this PR can be reviewed on its own, and no review of the entire stack is requested here.

The prepared branches are currently stacked. That branch order does not establish that every feature technically depends on this PR; independent changes can be separated where practical. Feedback on preferred scope or submission order is welcome.
