[Enhancement] Add Keyboard Shortcut Support for Chat Actions

[kareena0229]

Is your feature request related to a problem? Please describe.

Currently, most chat interactions depend on mouse clicks, which slows down workflow for users frequently interacting with PDFs and AI responses. Adding keyboard shortcuts would improve accessibility, usability, and productivity.

Describe the solution you'd like

Add keyboard shortcut support for common chat actions.

Suggested shortcuts:

• Ctrl + Enter → Send message
• Esc → Clear input
• Ctrl + K → Focus chat input
• Ctrl + Shift + C → Copy latest assistant response

Implementation can be handled using global keyboard listeners with useEffect inside chat-related components.

Describe alternatives you've considered

Users currently rely only on mouse interactions and manual navigation between chat actions. This works, but it is slower and less accessible for power users.

Additional Context

This enhancement would complement existing chat usability improvements like copy-to-clipboard and conversation branching features.
