Add drag-and-drop file support to terminal

[stevenvo]

Summary

• Adds drag-and-drop support for files in the terminal
• Uses Electron's webUtils.getPathForFile() to get full file paths from dropped files
• Automatically quotes paths containing spaces
• Supports multiple file drops (space-separated)

Changes

• emain/preload.ts: Import webUtils and expose getPathForFile API
• frontend/app/view/term/term.tsx: Add drag event handlers to terminal view
• frontend/types/custom.d.ts: Add type definition for new Electron API

Testing

Drag files from Finder onto the terminal - the full file path(s) should be inserted into the terminal input.

Walkthrough

This change introduces file drag-and-drop support for the terminal view by adding a new Electron API method. The implementation spans three layers: an Electron preload API method that resolves dropped files to filesystem paths, a TypeScript type definition for the new API, and terminal UI event handlers that collect dropped files, resolve their paths via the API, and send them to the terminal controller.
