TKO 4.0.0

TKO 4.0.0 is the first stable 4.x release.

Highlights:

• Stabilizes the full public @tko/* package set on the 4.x line
• Publishes stable 4.0.0 entry points for @tko/build.knockout and @tko/build.reference
• Uses GitHub Actions trusted publishing with npm provenance for public packages
• Keeps @tko/build.knockout as the migration-friendly default, with @tko/build.reference as the modular and TSX-oriented path
