/**
 * Test-file discovery and AC-reference scanning (FR2).
 *
 * Own walker + glob translator instead of `fs.globSync`: stdlib glob
 * semantics are release-dependent while the Node floor is 22.13; the pinned
 * semantics here are enforced by this module's tests (NFR1, design DD2).
 *
 * Pinned semantics (design Data Flow 4):
 *   - `**` matches zero or more path segments
 *   - `*` / `?` match within a segment, never a leading dot
 *   - dot-files and dot-directories are never traversed
 *   - exclusions (node_modules, .git, dist, build, .aidlc) prune before
 *     descent at any depth, regardless of glob source (AC-6/AC-7, DD4)
 *   - symlinks are never followed (AC-8, NFR3)
 *   - emitted paths are posix-separated and project-root-relative (design F7)
 *
 * Requirements: traceability-ids/AC-5..AC-8, AC-24, AC-25
