Task 4: Fix Python Named Groups

Wave: 1 (Critical Bug Fixes)
Category: unspecified-high
Parent: Epic #37

Problem

Python sub() creates empty HashMap for named groups (line 93), so \g{name} in replacements doesn't work. PyMatch also missing named_group() method.

What to do

RED: Write failing Python tests for sub() with named backrefs and named_group() method
GREEN: Fix ogex-python/src/lib.rs line 93 to pass actual named groups, add named_group() method to PyMatch
REFACTOR: Clean up Python bindings

Acceptance Criteria

ogex.sub(r"(name:abc)", r"[\g{name}]", "abc") returns "[abc]`
match.named_group("name") returns captured group text

Files

ogex-python/src/lib.rs:93 — empty HashMap for named groups
ogex-python/src/lib.rs:110-183 — PyMatch class
