refactor(license): remove dead Feature enum and isEnabled scaffolding

Browse Source 
Spec §9 — feature flags are out of scope for license enforcement.
Drops Feature.java, LicenseGate.isEnabled, LicenseInfo.hasFeature,
and the corresponding test cases. LicenseValidator now silently
ignores any features array on the wire (no error).
