[BUG] Windows - Deno executable not found (checks HOME, not USERPROFILE, and missing .exe)

[mynameistito]

packages/kernel/runtime-deno-subprocess/src/index.ts tries to find a locally installed Deno binary by checking HOME:

const home = process.env.HOME?.trim();
const installedPath = `${home}/.deno/bin/deno`;

On Windows, HOME is usually unset. The correct env var is USERPROFILE, and Deno installs to %USERPROFILE%\.deno\bin\deno.exe (with .exe).

Fix: fall back to USERPROFILE and use the correct Windows path.

Fixed in: packages/kernel/runtime-deno-subprocess/src/index.ts
