docs: add Future Vision section to README

- Added a new "Future Vision" section that acknowledges the current solution while being transparent about the ideal experience (native image paste in SSH clients like Termius with auto-upload and progress bar)
- Positions the project honestly on launch day while showing long-term ambition

This helps set the right expectations for users.

+## Future Vision
+
+PasteLocal already solves the core problem of reliably getting your local clipboard — especially screenshots — into remote agentic coding sessions over SSH.
+
+That said, we have a bigger vision for what this experience could become.
+
+The ideal workflow would feel almost native: paste an image directly in your SSH client (like Termius), have it automatically uploaded to the remote machine with a progress bar, and have the path instantly available in your agentic coding tool.
+
+We see PasteLocal as the foundation for deeper, more seamless integrations with terminals, SSH clients, and AI coding environments. If you're interested in helping push toward that future, we'd love to hear from you.
