scsi: promote SenseFamily to a lib-level SCSI-fact primitive

Browse Source 
Moved SenseFamily::from_sense_key + is_wedge_family from disc/read_error.rs
into scsi/mod.rs (with its own tests) and re-exported at the crate root.
This is pure SCSI sense-code classification -- objective hardware fact, zero
recovery-policy opinion -- so it belongs in the library primitives, unlike
the retry-DECISION state machine (ReadCtx/PassSummary/ReadAction/
handle_read_error) built on top of it, which is freemkv's specific recovery
strategy and is moving to freemkv-engine next.

disc/read_error.rs and disc/section_recover.rs now import SenseFamily from
crate::scsi instead of defining/re-exporting their own copy. No behavior
change. Precommit green on Rust 1.86 (fmt+clippy+test).
