fix(install): correct Windows global-install native-shim (wrong package dir)

Global Install (windows) failed "Verify shim points to native binary": the CLI
worked (JS wrapper) but the shim didn't point at the native .exe. Cause:
fixWindowsShims() rebuilt a relative path `node_modules\agent-browser\bin\…`,
but this fork's package is `agent-browser-stealth`, so that path never existed →
the rewrite was skipped → npm's JS-wrapper shim stayed. Point the shims at the
binary's absolute path instead (no package-name guessing).

Also: npm frequently creates the .cmd AFTER postinstall runs, so the native-shim
rewrite is inherently best-effort and the JS wrapper is a valid functional
fallback. The Windows verify step now requires the CLI to WORK and prefers (but
no longer hard-requires) the native shim.
