Fix RST badge rendering: disable override_image_directive

Set override_image_directive=False in sphinxcontrib-images config
to preserve standard RST image directive :target: option support.

This fixes badge substitutions in docs/index.rst that require the
:target: option for clickable badge links.

Note: This work was completed with AI assistance (Claude Code).
