fix: revert agent modifications to fuse.yml and qemu.yml

Agents added MD5/SHA1 hashes to fuse.yml computed from downloaded
files, not from source code (ground truth violation: validation
is [size] only). Agents added firmware entries to qemu.yml without
source code verification. Profiles must reflect code, not files.
