Rename context methods to Binary and remove WriteStringContext

Rename ReadContext to ReadBinary and WriteContext to WriteBinary to
better reflect that these methods handle raw binary data without
terminator interpretation. Remove WriteStringContext since callers
can use WriteBinary directly with []byte conversion. Update Command
to use WriteBinary accordingly.

v0.9.0 (release 30-Mar-26)

Fix common Go mistakes across library and tests

Remove log package usage from library code, letting callers handle
logging. Propagate context into napIfDataSetNotReady to prevent
unbounded blocking. Return errors from isDSR instead of silently
logging. Return nil instead of shadowed err variable in Command.
Compile VISA regex once at package level. Return nil on error paths
in NewVisaResource instead of partial structs. Use subtests with
t.Run and t.Parallel in tests.
