--detail now uses expandDeep to recursively resolve all cas_ref
fields in the detail merkle tree, showing full turn content
instead of raw hashes.
Refs #349
- Outputs markdown directly (not JSON/YAML)
- --quota <chars>: character budget, loads steps backward until exceeded (default 4000)
- --before <step-hash>: load steps before this hash (exclusive), omits start
- --start: force include start section even with --before
- --detail: expand detail CAS node content for each step
- Skip hint with uwf thread read command for pagination
- Reuses walkChain/collectOrderedSteps/expandOutput
Closes#349
