/**
 * Rewrite file_changed event paths to mounts-relative form.
 *
 * The bridge normalizer forwards tool filePaths verbatim — for Claude SDK
 * Write/Edit they are cwd-relative (e.g. "workspace/foo/bar.py" when cwd
 * is /skaile and the file lives at /skaile/workspace/foo/bar.py). The
 * frontend's file-change listener treats the path as relative to the
 * currently-selected mount, which double-prefixes when the workspace
 * mount sits under cwd.
 *
 * This helper resolves the path against cwd, locates the mount it falls
 * inside, and re-expresses the path relative to that mount with the
 * matching mountId attached.
 *
 * Events that already carry a mountId (watcher-originated) and events
 * whose path resolves outside every mount are passed through unchanged.
