The Windows unified agent exits at startup when HKLM\SOFTWARE\Microsoft\Cryptography\MachineGuid is a braced GUID. gopsutil v4.26.6 reads the value through a fixed 74-byte buffer and rejects any length other than 36, so a braced 38-character GUID fails the whole InfoWithContext call and newAgent aborts with 'fetch host info'. Recover the host info on Windows when the host-ID read is the failing field: read MachineGuid directly, strip braces and fill the other fields from gopsutil accessors, while keeping any non-host-ID failure fatal. Canonicalise Windows machine IDs by removing braces so both forms map to one stable agent identity. Includes agent-lifecycle contract section and focused proof in the registry-accepted agent_new_test.go. Windows recovery is cross-compiled with GOOS=windows; runtime execution on Windows is not qualified in this environment.
