Teknium 622c27e55c fix(install.ps1): restore EAP=Continue around uv python install, skip Store stub (#26586)
Fresh Windows installs were failing on first run with:

    ⚠ uv python install error: Downloading cpython-3.11.15-windows-x86_64-none (24.5MiB)
    ✗ Installation failed: Python was not found; run without arguments
      to install from the Microsoft Store...

Two bugs compounding:

1) EAP=Stop swallows uv's stderr progress as an exception. uv writes
   download progress ("Downloading cpython-3.11.15-windows-x86_64-none
   (24.5MiB)") to stderr. With $ErrorActionPreference = "Stop" set at
   the top of the script plus 2>&1 capture, PowerShell wraps each stderr
   line as an ErrorRecord and throws on the first one — even though uv
   exits 0 and Python was installed successfully. This was previously
   fixed in commit ec1714e71 (May 8) but lost in the May 12 release
   squash (413990c94). Reapply the EAP=Continue + verify-via
   'uv python find' pattern.

2) System-python fallback invokes the Microsoft Store stub. When the uv
   paths fall through, the legacy 'python --version' check invokes
   %LOCALAPPDATA%\\Microsoft\\WindowsApps\\python.exe, a 0-byte
   reparse-point stub that prints 'Python was not found...' to stdout
   and exits non-zero. Get-Command matches it. The resulting error
   message is what the user sees as the final installer crash. Detect
   and skip the stub by checking for the \\WindowsApps\\ path
   component or a 0-byte file size before invoking python.

Also save/restore EAP defensively in the catch blocks so a throw before
the assignment can't leave EAP in 'Continue'.
