Description

Fixes #8812.

With a base such as /docs/, a request for /docs/hello.txt can be recognized as static but is read from dist/docs/hello.txt, while the file is actually at dist/hello.txt. Build and asset directory prefixes also omit the base.

Use the configured base for build/asset classification, then strip it at the filesystem boundary in the Node, Deno, and Bun middleware. Preserve full URL paths in the prerendered-path lookup and keep the existing trailing-slash behavior. Deno and Bun derive the filename from the stripped pathname too.

Filesystem access still follows static-path eligibility checks, and the base must match at a slash boundary. Encoded path segments remain encoded.

The focused suite covers public files, nested bases, root/index pages, both trailing-slash modes, build/assets without manifest entries, and paths outside the base. All 50 tests pass; restoring the original production implementations produces 23 failures.

Validation:

• pnpm build.core and the Router TypeScript check pass.
• Changed-file ESLint, Prettier, and diff checks pass.
• The package unit suite passes with one existing loopback-socket test excluded: 3673 passed, 20 skipped (19 existing skips plus that exclusion), and 19 todo. The excluded test is should make Node response progress before render completes; this environment does not permit its localhost listener.
• Deno/Bun adapter tests use real filesystem-backed API shims under Node. Native runtime and browser E2E tests were not run.
