fix: module 10 review round 1 (module-local SpellGrid cards, cast target check, CLI without panic hook)

- SpellGrid cards move to course/10-spellgrid/cards; start-module and
  verify-references stage course/cards plus module-local cards up to the module,
  so M5-M9 workspaces get exactly the pre-M10 card set.
- cast() rejects a chosen-target spell without a target (checkCast/checkPlay);
  new test_10_targeted_spell_needs_target.
- Rust CLI pre-validates instead of swapping the global panic hook.
- Catalog: CRIER noun; DEATHRATTLE/BATTLECRY note on lexicon vs catalog role.
- Lesson: design note on mid-movement reparse.
