feat: increase vault context limits and make them configurable

- Replace hardcoded 2000-char context limit with configurable maxContextLength
  setting (default: 8000 characters)
- Increase vaultSearchLimit default from 3 to 5 notes
- Add 'Max Context Length' setting to plugin settings UI
- Update README with new defaults
- Update chat-view tests for new setting
