feat(editor): add --list-packs introspection + --gen-temple-pack

Two related changes:

  • --list-packs walks kArgRequired and surfaces every flag
    matching --gen-*-pack (excluding --gen-mesh-* and
    --gen-texture-* which are individual primitives). Sister
    command to --list-primitives. Auto-tracks new packs as
    they're added — no parallel registry.

  • --gen-temple-pack composite — temple/shrine ritual hall
    (altar + shrine + brazier + pillar + statue + portal +
    podium). Fourth themed mesh pack after camp / blacksmith /
    village.

list-packs now surfaces 9 composites including the pre-
existing zone-* / project-starter packs that match the
naming convention. All 7 temple-pack outputs validate clean.
