Module truncation 

Tool output truncation with temp file overflow.

When tool output exceeds size limits (lines or bytes), the full output is saved to a temp file under ~/.opendev/tool-output/ and the agent receives a truncated preview plus the file path for follow-up reads.

Mirrors OpenCode’s Truncate system.
