When running Fresh 2 in development, the ETag caching was leading toincorrect assets being served. I'd often get stale assets from days agoor separate apps. This problem was especially bad with multiple appsthat run on the same port. For example, I may work on App A on thedefault port 5173. Then boot up App B. I'd get assets from App A when Iwouldn't want them, leading to a frustrating dev experience.

Sets up `@/` as the default path alias in newly generated Freshprojects, following the official Deno documentation guidelines. Thisallows developers to use `@/` for absolute imports from the project rootinstead of relative paths. This is especially convenient to removeimport that require deeply traversing up the directory tree.The `@/` alias is now included in the imports section of deno.json forall new projects, enabling cleaner import statements like:```import { Button } from "@/components/Button.tsx";```Fixes#3485

The Vite plugin was not filtering out test files from route discovery,causing test files in routes/ (e.g., routes/api/counter_test.ts) to bebundled into production builds, inflating bundle sizes by ~20KB per testfile and including unnecessary test dependencies.Root cause: Vite plugin defaulted ignore patterns to [] while Buildercorrectly defaults to [TEST_FILE_PATTERN].This fix:- Defines TEST_FILE_PATTERN in shared constants.ts for reusability- Exports TEST_FILE_PATTERN from internals_dev.ts for Vite plugin access- Updates Vite plugin default from [] to [TEST_FILE_PATTERN]- Updates Builder to import TEST_FILE_PATTERN from constants.ts- Ensures test files matching /[._]test\.(?:[tj]sx?|[mc][tj]s)$/ areexcluded- Adds integration test to prevent regression- Allows Deno best practice of colocating test files without bundlingthemTest coverage (prevents regression):- Unit test: walkDir respects skip patterns- Unit test: crawlRouteDir excludes test files- Integration test: Vite builds exclude test files from outputFixes#3558
