⚡ Bolt: Replace DirtyJson.parse_string with dirty_json.try_parse

[thirdeyenation]

💡 What: Replaced direct calls to DirtyJson.parse_string with dirty_json.try_parse.
🎯 Why: dirty_json.try_parse tries json.loads first, which is heavily optimized C code, and falls back to DirtyJson.parse_string only when the JSON is malformed. Calling DirtyJson.parse_string directly uses a slower python-based parser even for well-formed JSON strings. This was identified as a bottleneck in the Bolt journal.
📊 Impact: Considerably faster parsing for all JSON strings generated by LLM that are well-formed. This directly improves the execution speed of MCP handlers, memory consolidation loops, browser agent processing, and general streaming JSON processing in the agent.
🔬 Measurement: Run unit tests and benchmark the execution loop duration with well-formed JSON strings to observe the performance difference.
