[Tejas Lamba (TejasLamba2006)]

Fixes #151.

While checking #151 against recorded Claude Code transcripts on my machine, I noticed two places where response_text feeds edited file contents into ERR_RE:

1. Edit returns {filePath, oldString, newString, originalFile, structuredPatch, ...} with none of _RESPONSE_KEYS, so response_text fell back to json.dumps(resp).
2. Write returns {type, filePath, content, originalFile, structuredPatch, ...}, where content is the written file body.

Replaying response_text across 964 local Claude Code session logs (37,797 structured toolUseResult dicts), 12,279 successful Edit/Write calls matched ERR_RE before this change and 0 after. Real edit failures still arrive through PostToolUseFailure (_failure_response), which carries error without structuredPatch.
