* fix: update codex config tests to match simplified config structure
Tests asserted the old config structure ([features] section, multi_agent,
default_mode_request_user_input, [agents] table with max_threads/max_depth)
that was deliberately removed. Tests now verify the new behavior: config
block contains only the GSD marker and per-agent [agents.gsd-*] sections.
