feat: Value type methods — chain calls on String/Array/Numeric/Hash

Built-in methods on basic types, enabling fluent chaining:
  cStr:Trim():Upper():Left(5)    → "HELLO"
  aArr:Sort():Join(",")          → "1,2,3"

String (20 methods):
  Upper, Lower, Trim, LTrim, RTrim, Left, Right, Substr,
  Len, Replace, Split, Contains, Starts, Ends, Reverse,
  Replicate, Copy, At, Empty, Val

Array (14 methods):
  Len, Push, Pop, Sort, Find, Map, Filter, Each,
  Join, Copy, Empty, First, Last, Slice

Numeric (6 methods):
  Str, Round, Int, Abs, Sqrt, Copy

Hash (7 methods):
  Keys, Values, Has, Len, Copy, Delete, Empty

Any type (5 methods):
  Copy, Type, IsNil, ToStr, ClassName

Integration: Thread.Send() checks SendBuiltin() before class dispatch.
Tests: 28 tests ALL PASS including chaining test.
