fix: wizard "No JSON found" — Claude CLI stream-json returns empty result field

Browse Source 
Claude CLI's --output-format stream-json now returns "result": "" in the result
message. The actual response text lives in assistant message text blocks, which
_textOutput correctly accumulates. runPrompt() was returning the empty
resultMsg.result without falling back to _textOutput.value.

Also improved plan-orchestrator JSON extraction to try code-block-wrapped JSON
first (```json {...} ```) before the greedy regex, plus debug logging.
