Fix install.sh breaking on fresh installs (Issue #42 by @jeanchastel):
- Sparse-checkout cone mode: removed file args that caused
skills/andhooks/to be pruned. Cone mode only accepts directories; root files are included automatically - Checksum fallback: installer now falls back to in-repo CHECKSUMS.sha256 when the release asset is missing, instead of hard-failing
- CHECKSUMS.sha256 asset: now attached to releases for out-of-band integrity verification
- bash_compress.py: added missing
from __future__ import annotations(caught by new regression eval)
Thanks @jeanchastel for the thorough bug report!
