fix(codeagent-wrapper): remove 150-char truncation limit for KeyOutput in summary mode

maxLen=0 in extractKeyOutputFromLines now means unlimited, so the
orchestrator receives the agent's full concluding summary instead of
a 150-character stub. Negative maxLen still returns empty. Structured
summary format and log-path-only behaviour are preserved.
