Subject: [PATCH] fix(scan): use fileURLToPath for the entrypoint scan root

scanQwikEntrypoints used config.root.pathname as the grep cwd and as the
base for resolve(). On Windows that value is "/C:/project/", which is not
a valid filesystem path: spawn fails with ENOENT, the error is swallowed,
no entrypoints are found, the standalone client build is skipped, and
every QRL reports Q14 during prerender.

Convert the root URL with fileURLToPath so the cwd and the resolved
absolute paths are native on every platform. Add unit tests that scan a
real temp directory.
