Markus Fritsche b5e7e2b632 sicd: implement wire protocol (preamble + nested netstring peeling) ...

- Read preamble: magic byte \x00 + 4-byte BE length + netstring
- Split netstring at first NUL: command\0<payload>
- Exec command with payload + trailing stdin forwarded
- Nested payloads are netstrings for the next hop (one layer peeled per sicd)
- Bare -- survives as opaque data
- Malformed input: exit 1 with stderr diagnostic
- 14/14 pytest green
