chore(build): ship only the DTLN files that can load (-9 MB) (#210)

The DTLN noise-suppression package was copied whole into every build
(57 MB). Its threaded LiteRT build is only used on a cross-origin-isolated
page, and neither the web nor the desktop call page is (no COOP/COEP), so
its ~9 MB could never load; source maps and .d.ts files aren't needed at
runtime either. Leave those out: 57 -> 48 MB per web deploy and desktop
installer. Verified on the built output, not isolated: the DTLN worklet
reaches ready and runs a 300-frame benchmark, no 404s.
