Show tool call arguments inline instead of JSON blob

- Add formatToolCallSummary to extract key argument from JSON
- Shows run_bash command, file paths for read/edit/write, patterns for search
- Display summary inline in tool call header (e.g., run_bash: `ls -la`)
- Increase token guardrail from 1M to 2M to prevent premature stops
