fix: agent prompts use run_tests MCP tool instead of running script/test via Bash
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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
