Module parse

Expand description

2026-09-26: Pure parsers for the nvidia-smi, procfs and sysfs text that super::collect reads.

Owner: bench hardware. Invariants:

&str in, data out: no I/O, so the fixtures in fixtures/ exercise every parser.
A number that does not parse is None, or its row or zone is dropped; no parser substitutes a default, so a caller can tell “0 µs of throttling” from “no idea”.
