feat: Disable Copilot, increase terminal font, disable port forwarding

Changes to devcontainer.json:
- Disabled GitHub Copilot (github.copilot.enable: false)
- Disabled inline suggestions (github.copilot.inlineSuggest.enable: false)
- Disabled chat command center (chat.commandCenter.enabled: false)
- Increased terminal font size to 14 (from default 12)
- Commented out automatic port forwarding (8000, 8080, 3000)

Users can still manually forward ports if needed via VS Code UI.
