Bounded-cache buffered File replacement used across mux/extract/sweep/patch
-- general I/O infrastructure, not recovery policy. freemkv-engine's
relocated sweep/patch need to construct it directly once those methods
leave this crate. No behavior change.
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).
The upcoming freemkv-engine crate needs both to build the multipass
sweep/patch recovery strategy externally over Disc's public API. Everything
else sweep/patch touch on Disc was already pub; these were the only two
gaps. No behavior change -- visibility only.
