Copilot 03b8e8fdde Python: refactor getChild into per-class OO dispatch

Replace the single ~240-line top-level getChild predicate with one
override per AST class. AstNode declares a default

  AstNode getChild(int index) { none() }

and each subclass with children overrides it (41 classes total).
The top-level predicate becomes a one-line dispatch:

  AstNode getChild(AstNode n, int index) { result = n.getChild(index) }

No behavioral change: NewCfg evaluation-order tests still pass at the
same 22/24 baseline, and all 11 shared-CFG consistency queries still
report 0 violations on CPython.
