Modul 01 Hotfix A4: AnvilRecipe.IsCollectable ergänzt

01-RecipeData Rev 6 (A4) added the field as a Summarize-branch
discriminator for module 02. Resolved as IsExpertRecipe OR the
output item's AlwaysCollectable flag, the latter being the canonical
FFXIV signal for collectable submissions (custom delivery, masterpiece
supply, collectables shop).

- AnvilRecipe.cs: new required bool property after CanHQ, with a
  why-comment pointing at module 02's Summarize branch and noting
  the OR-resolve.
- LuminaRecipeAdapter.cs: resolve folded into the recipe walk via
  the same itemSheet.TryGetRow call that already fetches the
  display name - no bootstrap-order question, no 2-pass needed.
  hasOutputItem is hoisted so the OR-branch can guard against a
  missing item-sheet row without touching the default(Item) struct.
- RecipeDataAdapterLoadStep.cs: new pass criterion #10 that asserts
  at least one recipe surfaces IsCollectable == true. Catches a
  silent resolve-path failure. Existing Cosmic-surface check shifts
  to #11 to keep numbering stable.

Build clean (0/0), csharpier clean.
