Fusion - the Fusion 360 Bridge

#!/usr/bin/env bash
# Phase 4, the package flip (run ONLY on John's word): the release becomes the Rust exe alone.
#   - bridge.json: spawn.kind exe, entrypoint adom-fusion-bridge.exe, no python dependency
#   - tools/release-files.txt: the Python bridge and its helpers leave the zip (describe.py stays
#     a BUILD-time input for freeze-contract; the add-in tree and resources ship as before)
#   - tools/release.sh keeps its contract freeze and the exe build; the python import checks go
# Idempotent; prints what changed; commits nothing. Review the diff, then tools/release.sh.
