Function: sourceCapabilities()

function sourceCapabilities(source): SourceCapabilities;

THE kernel-side accessor for a source's capabilities (TS twin of the Py source_capabilities). Resolution order (memoized per instance):

1. the adapter's own capabilities() returning a SourceCapabilities — the explicit declaration;
2. DEPRECATED fallback: deriveCapabilities structural probing, with a once-per-constructor console warning pointing at the migration (keeps external adapters working).
