(feat/canvas): Add Spreadsheet Support (wip)

[nickscamara]

WIP - feedback + improvements are very welcomed!

Adds Spreadsheet support to the canvas

• Adds interactive sheet functionality to the AI chat interface, allowing users to:
  • Use AI to generate and manipulate spreadsheet content
  • Create and edit tabular data
  • Export data to CSV format
  • Navigate cells using keyboard shortcuts
  • Add/remove rows and columns

Known Issues:

• There are still some rendering/layout shifting issues with the custom spreadsheet component (wip)
• Still need to nail the cell clicking+highlighting animation/ux
• Editing cells and moving throughout the spreadsheet is not very smooth
• Light mode only currently

Little Demo:

Thanks @jaredpalmer for suggesting me to open a PR for this.

@nickscamara is attempting to deploy a commit to the Vercel Team on Vercel.

A member of the Team first needs to authorize it.

This is really cool! Once you're done with this I'd love to extend it further to allow upload of csv files, which can then be edited like this.
