Shell Window Feature

Purpose: Interactive pseudo‑terminal session inside a krate.

Implementation:

Front‑end component uses xterm.js (or equivalent) for terminal UI.
Backend opens a WebSocket that proxies to kubectl exec -it <pod> -n <ns> -- sh (or the container's default shell).
Input handling: when the mouse is over the shell window, all keypresses are forwarded to the terminal; space does not trigger Spotlight.
Scroll wheel over the terminal scrolls its content; Ctrl/⌘+scroll still zooms the canvas.
No PTY needed on the server side beyond the exec stream; the WebSocket carries stdin/stdout/stderr.

Interaction:

Click a result in Spotlight or Collection and press Alt+S to open a Shell window in a new/existing Krate.
Resize like any Detail Window; sibling windows resize proportionally.
Double‑click header or press z to maximize to the viewport.
The shell window obeys the global pan/zoom shortcuts (Space‑drag pans, Ctrl‑scroll zooms) when the cursor is inside it.

State (Window type shell).
