Handle the case where Claude Code exits without producing a result line
(timeout, OOM, signal kill). Previously returned null and threw an error;
now returns incomplete result with best-effort output extraction.
Changes:
- Add "incomplete" as new ClaudeCodeResultSubtype value
- Extract output from last assistant turn when no result line exists
- Enhanced error messages distinguish incomplete vs unparseable output
- Store incomplete results in CAS with appropriate metadata
- Add 10 comprehensive test cases for incomplete result handling
Fixes#574

Switch from --output-format json to stream-json --verbose to capture
per-turn data. Detail now includes:
- model name
- usage (input/output/cache tokens)
- stopReason
- turns[] as individual CAS nodes with role, content, tool calls
Also addresses PR #421 review fixes:
- sessionId guard: skip cache write when sessionId is empty/undefined
- silent catch: log resume failures with debug tag 5VKR8N3Q
- atomic write: session cache uses temp+rename for crash safety
Closes#422
Claude Code CLI adapter for the workflow engine, mirroring
workflow-agent-hermes architecture. Spawns `claude -p` with
`--output-format json` for structured output parsing.
