# Prune files/directories that accidentally live under scripts/ but must
# never ship inside the built bundle. Runs under `cmake -P` — portable
# across Windows / macOS / Linux.
#
# Rationale:
#   - *.deleted.* / *.bak / *.orig  — leftover backups from refactors
#   - .pytest_cache / .benchmarks   — pytest caches committed by mistake
#   - __pycache__                   — Python bytecode caches
#   - *.db / *.sqlite*              — local SQLite DBs (e.g. memories_alice.db)
#
# On macOS anything unexpected inside an .app bundle trips codesign with
# "bundle format unrecognized, invalid, or unsuitable". On Linux/Windows
# these just bloat the installer; removing them shrinks it meaningfully.


# `cmake -P` starts with every policy OLD, which turns the IN_LIST operator
# below back into a plain string comparison (CMP0057).
