/// existing regular file. Relative spellings resolve against `base_dir` (the
/// document's own directory), matching arity's `source()` resolution; absolute
/// spellings (and any when `base_dir` is `None`) are taken verbatim. A pure CST
/// walk plus one `stat` per literal — no semantic model, no workspace snapshot.
///
/// Documents larger than `file_size_limit` bytes are skipped wholesale so link
/// discovery never walks a pathological generated file. Targets are resolved
/// eagerly (no `documentLink/resolve` round-trip); a resolve provider could be
/// added later if the per-literal `stat` ever shows up in a profile.
