Behavior is a newtype (Behavior(pub u16)), not an enum, so the 5 test
call sites that passed Behavior::PURE / Behavior::IO_HEAVY / etc. directly
to the ev() helper got type mismatch errors. Add a local behavior() wrapper
and use it at all 5 sites. Also clean up the unused CodeCell import and
extraneous parens that clippy flagged.
fix(cubesys): ls on directory paths no longer rejected by path_to_czyx
The ls handler used path_to_czyx() (which enforces "path must name a
record") to derive the ACL gate coordinate. Directory prefixes like
/c001/z001/y001 are valid read targets but path_to_czyx rejects them as
"names a directory, not a record", so cube-bench's ls assertion panicked.
Fix: use cubefs::path::parse_path (accepts any well-formed prefix) and
derive the directory prefix coordinate (trailing axes zeroed) for the ACL
gate, matching what NullSpace acl_bucket uses for directory ACLs.
Verification: cube-bench runs to completion (ls section printed OK), all
3 cubetrace tests pass, workspace compiles clean.

Brings in the cubetrace crate (PDF Package 4, §547): wraps a DBI engine via an
FFI seam and streams trace events (basic blocks, syscalls) into cubestore,
tagging each with CZYX coordinates and header flags.
- Cargo.toml: register cubetrace workspace member
- cubeai/src/lib.rs, cubedbt/src/lib.rs: DBT/AI rule + trace integration edits
- cubecode/src/{cb,cell}.rs: code-cell bytecode/module plumbing for traces
- cubesys/src/commands.rs: trace/AI command surface expansion
- cubetrace/: new crate (builds; 2 non-fatal warnings)
All layers of the OS-in-CUBE migration pass; recorded per user green-light.
