 * Read the source files Stryker will mutate (the `mutate` glob set), so the
 * dynamic-LLM pre-pass can target them. Resolves each match against `projectDir`
 * to the ABSOLUTE fileName the pre-pass + reporter key on.
 *
 * Uses Node 26's `glob` from `node:fs/promises` (an async iterator). It yields
 * paths RELATIVE to its `cwd` option, so each match is resolved against
 * `projectDir`. Negated `!`-patterns are not handled (matching the prior Bun
 * behaviour): each pattern is treated positively. An absent/empty `patterns`
 * falls back to {@link DEFAULT_MUTATE_PATTERNS}.
 *
 * @param projectDir The project root the globs and absolute fileNames resolve against.
 * @param patterns The `mutate` globs (the resolved Stryker `mutate` value), or empty for the default.
 * @returns Absolute-path source files (`{ fileName, content }`), de-duplicated.
