Summary

• add a new main-process debug collector IPC (debug:collect) that builds a sanitized diagnostics payload
• include app/runtime metadata, project/session counts, MCP config summaries, OAuth file presence, and log label/error summaries
• redact likely secrets and strip private path details from exported diagnostics
• save each generated bundle to oagent-data/debug-reports/debug-info-*.json
• add Settings UI action: Settings → General → Copy Debug Info to copy a GitHub-ready JSON block
• expose the new API through preload and renderer typings
• update bug reporting guidance in .github/ISSUE_TEMPLATE/bug_report.yml and CONTRIBUTING.md

Validation

• code-level verification of wiring from IPC handler to renderer button
• local TypeScript build could not be executed in this environment because node_modules/.bin/tsc is unavailable
