Copilot 93112b2b75 Python: include try-else in getChild for completion propagation

The shared CFG library propagates abrupt completions from child to
parent via getChild(parent, _) = child. Python's try.getElse() was
wired into normal step rules but not listed in getChild(TryStmt, ...),
so return/break/continue/raise statements occurring inside a try-else
block had no parent path and ended up as dead-end CFG nodes.

Add the else block at index -2 (alongside finally at -1). This affects
only completion propagation; the normal-flow CFG is unchanged because
TryStmt has explicit step rules.

Verified on a CPython database: all 11 shared-CFG consistency queries
now pass with 0 violations (deadEnd: 244 -> 0).
