feat: lib-core.crafting v0.1.0 — Recipe Registry + Craft Action

Headless data + logic layer for recipe-based crafting. Manages a
recipe registry, performs match-checks against a container's
inventory contents, and atomically consumes inputs + creates outputs.

Surface:
  define_recipe{id, inputs, output, name?, description?, is_known?}
  list_recipes(), get_recipe(id)
  is_known(recipe_id, ctx)              -- per-recipe discovery gate
  can_craft(recipe_id, container, ctx)  -- non-mutating availability
  craft(recipe_id, container, ctx)      -- mutating action

Recipe-Schema: count-form inputs (array of {template, count}) +
single output {template, count} + optional is_known(ctx) hook
(default returns true). Match-result schema:
  { ok=true, crafted_items, consumed }
  { ok=false, error='unknown_recipe' }
  { ok=false, error='missing_inputs', missing={{template, needed, have}} }

Container is both inputs-source and output-destination (single-container
v0.1; multi-container deferred). craft re-runs can_craft internally
and returns the structured error if state changed since the last frame.

Depends on lib-core.composition 0.3.0 (template_of, create, destroy)
and lib-core.inventory-list 0.1.0 (contents, add, remove).
