Agents were running script/test directly through the PTY, streaming
the full output of npm install, cargo clippy, cargo test, and frontend
builds into session logs. This tripled session log sizes (~200KB to
~600KB per session) and contributed to CLI SIGABRT crashes.
The run_tests MCP tool already runs script/test server-side and returns
a truncated JSON summary. Agents now use it exclusively.
