feat: support new Ladybug C API features

[adsharma]

• Added PreparedStatement#isReadOnly().
• Added enableDefaultHashIndex constructor argument to Database.
• Added low-level Arrow C Data Interface registration methods:
  • Connection#createArrowTableSync(...)
  • Connection#createArrowRelTableSync(...)
  • Connection#dropArrowTableSync(...)
• Expanded parameter conversion:
  • empty lists now bind as empty LIST instead of null
  • nested nulls are typed correctly
  • mixed list/map values widen like the C API behavior
  • Map parameters bind as Ladybug MAP values
  • added lbug.json(value) for JSON-typed parameters
• Updated TypeScript declarations and tests.
