fix(nx-infra-plugin): resolve glob pattern failures on Windows

The glob library requires forward slashes as path separators across
all platforms, but path.join() creates backslashes on Windows. Glob
interprets backslashes as escape characters rather than path
separators, causing pattern matching to fail and executors to
process zero files on Windows.

Created normalizeGlobPathForWindows() utility function and applied
it to build-typescript and add-license-headers executors. Also
changed empty file list from warning to error for fail-fast
behavior.
