Subject: [PATCH] fix(ci): unblock install and wire INTERSCRIPT_MAPS_PATH
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- setup.py: drop the legacy build gate that required ./build.sh
  compiled maps — the runtime parses .imp directly and never ships
  src/interscript/maps
- interscript.py: seed _load_paths from INTERSCRIPT_MAPS_PATH so the
  public API finds maps without an explicit add_load_path
- test_engine: reset paths via the implementation module
