Fractured: Paragon core hooks, mod-paragon, mod-ale, Docker build cap

- Track mod-paragon and mod-ale (un-ignore modules in .gitignore).
- Ship docker-compose.override.yml with CMAKE_EXTRA_OPTIONS for LuaJIT (mod-ale).
- Dockerfile: CBUILD_PARALLEL default to limit OOM under Docker/WSL2.
- Core: CLASS_PARAGON sticky combo points (DetachComboTarget), selection rebind,
  Spell::CheckPower rune path for multi-resource Paragon.
- spell_dk_death_rune: IsClass(CLASS_DEATH_KNIGHT, CLASS_CONTEXT_ABILITY) for
  Blood of the North / Reaping / DRM on Paragon.
- Remove temporary Paragon CheckPower logging.
