feat: improve inspector UI for processes and fix PTY terminal

- Simplify ProcessRunTab layout: compact form with collapsible Advanced section for timeout/maxOutputBytes
- Rewrite ProcessesTab: collapsible create form, lightweight list items with status dots, clean detail panel with tabs
- Extract error details: use problem.detail instead of generic "Stream Error" title for better error messages
- Fix GhosttyTerminal binary frame parsing: handle server's binary ArrayBuffer control frames (ready/exit/error)
- Enable WebSocket proxying in Vite dev server with ws: true
- Set TERM=xterm-256color default for TTY processes so tools like tmux, vim, htop work out of the box
- Remove orange gradient background from terminal container for cleaner look
- Remove orange left border from selected process list items
- Update inspector CSS with new process/terminal styles
