refactor(debug): replace ConsolePatcher with debugLogger and update error reporting

- Replace ConsolePatcher with centralized debugLogger utility
- Refactor errorReporting to use debugLogger instead of file-based reporting
- Remove user-facing console message components:
  - Delete ConsolePatcher.ts, useConsoleMessages.ts/hook
  - Delete ConsoleSummaryDisplay.tsx, DetailedMessagesDisplay.tsx
- Update all tests in packages/core and packages/cli:
  - Mock debugLogger where needed
  - Remove assertions for console output on non-critical errors
  - Keep debugLogger assertions for fatal/network errors
  - Use HOME directory mocking for hermetic file system tests
