Add unblob so REA can extract firmware

Browse Source 
unblob 26.6.4 (the version REA is verified with) is installed from its
PyPI wheel into /opt/unblob, with dependencies pinned to its uv.lock at
the release commit. A wrapper puts that venv first on PATH, and
REA_UNBLOB_COMMAND points REA's extract_firmware at it.

Its extractors follow upstream's install-deps.sh: Ubuntu packages,
sasquatch v4.5.1-6 (also used by binwalk) and onekey-sec's e2fsprogs
fork, whose debugfs rdump options the ext2/3/4 handler needs. The build
checks that unblob finds every extractor.

The uv.lock converter moves to scripts/ and skips the locked project
itself generically, since ghidra-mcp and unblob both use it.
