…red chunk consistency - Strip trailing slashes when resolving relative directory imports in `createMemoryFileLoaderPlugin` so `./dir/` resolves `.../dir/index.js`. - Support `.cjs` and `.d.cts` extensions, and prioritize `.d.mts`/`.d.cts` before `.d.ts` when resolving explicit `.mjs`/`.cjs` specifiers in `.d.ts` mode. - Treat Windows drive-letter absolute paths (`/^[a-zA-Z]:\//`) as internal modules. - Fall back to on-disk declaration files in `.d.ts` mode for hand-authored ambient/declaration files not emitted into the in-memory `dtsFiles` map. - Re-bundle all entry points from in-memory outputs during partial watch rebuilds when previous bundle results contained shared chunks to prevent inlining shared code into a subset of entry points.
