perf: startup instrumentation and npm install#208
Merged
Conversation
Add comprehensive tracing instrumentation across the entire agent startup path (gigacode CLI, ACP HTTP adapter, agent installation, and process spawning) to enable detailed performance profiling. Replace npm-based agent process launchers that use npx (incurring resolution overhead on every spawn) with pre-installed npm packages, reducing startup latency. Improve error diagnostics when agent processes crash by capturing exit codes and stderr tails. Update error handling to map exited processes to dedicated error variants with actionable error messages. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

Summary
Improves agent startup performance by replacing npx-based launchers with pre-installed npm packages, reducing resolution overhead on every spawn. Adds comprehensive timing instrumentation across the entire startup path (CLI, HTTP adapter, agent installation, process spawning) for detailed performance profiling. Improves error diagnostics when agent processes crash.
