 * Examples:
 * - `/a/b/c/d/**` + `/a/b/c/d/efg.txt` -> `efg.txt`

 * Return destination of files individually relative to output dir.
 * For example, if `viteConfig?.build.outDir` is set to `dist`, then
 * - when `dst == undefined`, then file would be stored inside `viteConfig.build.outDir` or `writeBundleOptions?.dir` or `dist/`
 * - when `dst == "./foo/bar"`, then file stored in `${viteConfig.build.outDir}/foo/bar/`
 * - ```({dstFile}) => `.cache/${dstFile}` ```, then file stored in `${viteConfig.build.outDir}/.cache/`. NOTICE! no slash at beginning
 * - This also can ```({dstFile}) => `../.static/${dstFile}` ``` which store file in `${viteConfig.root}/.static/`, the same level as `viteConfig.build.outDir`
 * - `() => false`, then the file would be excluded. Good for complex ignoring files
 * - , then file is manually named, and current built-in naming would be ignored. Good for complex use-case or need massive modification
 * ```ts
 * ({
 *   {__dst, ...opts}, __files, // muttable
 *   dstFile, filepath, baseFile, // useful params to use
 * }) => {
 *   __files["new-no/existing/file.png"] = "/home/me/Pictures/image.png"
 *   return false;
 * }
 * ```
 * - `() => undefined`, then it would going with default
 *
 * **NOTE:** string must return either absolute path or relative path in POSIX without beginning slash. It must also return forward slash.\
 * NOTE: the default actually put inside `__dst` not `viteConfig?.build.outDir` \
 * NOTE: Please ALWAYS use posix slash, rather than win32 backslash
