crafting v0.5.0 + composition v0.4.0: Quality & Condition (Phase J)

lib-core.composition v0.4.0: un-defer quality/condition as inert numeric
properties (loud-error removed); composition stores them without semantics.

lib-core.crafting v0.5.0: quality-block (multi-contributor product-quality
formula: skill-band with min=requires-floor + named ingredient/tool qualities),
optional slot name, tool wear_per_use (condition decrement + wear report).
affordance stays boolean. Additive to v0.4.0.

vagrant-skeleton v0.22.0: branch quality-band RNG at spawn; stone_hammer
condition=1.0; knap+axe quality-blocks; hammer wears out. Headless-verified 20/20.
