feat(recipedata): add plain-data records and enums

Module 01 public-API surface: six sealed records with init-only
properties plus their nine enums. All BCL-only - no Lumina or Dalamud
types in any public property, which is what keeps the simulator and
catalog xUnit-testable per the Critical Boundary in 00-Anvil-Scope §3.3.

- AnvilRecipe + AnvilRecipeIngredient: flat representation of the
  Recipe + RecipeLevelTable sheet pair with the five Cosmic-Exploration
  flags. v0.1.0 ships with MissionHas* always false (SH-15 option B);
  the schema stays in place so v0.2.0 can wire the WKS mission sheet
  without touching the type.
- AnvilItem: slim per-recipe / per-food item view (full ~50k-row item
  mirror is left to the UI layer).
- AnvilAction + AnvilActionKind + AnvilActionCategory + AnvilActionFlags:
  one logical action per Kind value with RowIdByClassJob mapping; Cosmic
  actions use ClassJobId 0 as the sentinel for "every crafter".
  AnvilActionFlags bit 1 << 2 is intentionally vacant (ConsumesGreatStrides
  was removed in spec rev 5; consumption logic lives in 02-CraftingSimulator).
- AnvilBuff + AnvilBuffKind + AnvilBuffBehavior + AnvilBuffCategory:
  static buff catalog entry with the duration field that matches Behavior
  (Steps / Seconds / Actions). Two Cosmic buffs (MaterialMiracleBuff,
  StellarSteadyHandBuff).
- AnvilCondition + AnvilConditionKind: eleven conditions including the
  Cosmic Robust variant. DisplayName comes from AnvilStrings.resx, not
  Lumina (the Status sheet does not expose the crafting condition labels
  cleanly).
- AnvilFood + AnvilFoodBonus + AnvilFoodKind + AnvilFoodStat: ItemFood
  mirror with IsRelative flag (percentage vs flat bonus).
