crafting: retire form, unify on affordance capability axis (ADR-0055 amendment)

Browse Source 
Recipe roles now match on a single `affordance.*` axis, required by both consumed `inputs` and non-consumed `tools` (the inputs/tools split carries consumption, not a separate axis). `form` — which conflated geometry, identity and capability — is removed. Its functional members folded into affordances (blade->cutting, shaft->leverage, plus knappable/spinnable/binding); identity members became template-id (chop_tree) or material+weight (log, hammer head).

vagrant-skeleton v0.20.0; no crafting/composition lib bump (they never knew `form`). Verified headless via the tool-harness: 16/16 checks pass — role-flexibility (stick OR branch hafts), weight discrimination, tool-gating (tool not consumed), and anti-recursion guards (sharp_stone not re-knappable, cordage not re-spinnable).

-- content/stone_age.lua — T1-modder content pack: Stone-Age items + recipes.
--
-- PURE CONTENT via the authoring API `c` (see init.lua's content facade):
-- c.T{ id, name, desc, weight, vol, form=, material={...}, affordance={...},
-- c.T{ id, name, desc, weight, vol, material={...}, affordance={...},
-- atlas="tc"|"stone", uv="<sprite-key>", scale? } -- define an item
-- c.R{ ...crafting.define_recipe def... } -- define a recipe
-- c.S{ template, x, y } -- place item in world
--
-- ROLE-BASED RECIPES (the intent): a recipe slot asks for the ROLE it needs,
-- and ANY item that fills that role qualifies — not a specific item id. Roles
-- are expressed as property-constraints (crafting v0.3 / ADR-0055):
-- * `form` — physical role: shaft / cord / fiber / lump / blade / …
-- ROLE-BASED RECIPES (the intent): a recipe slot asks for the CAPABILITY it
-- needs, and ANY item that offers that capability qualifies — not a specific
-- item id. Capabilities are expressed as property-constraints (crafting v0.3 /
-- ADR-0055 + its 2026-07-31 amendment). Two orthogonal axes carry a recipe:
-- * `affordance.*` — what an item OFFERS / can DO / what role it fills:
-- cutting / hammering / chopping / leverage / binding /
-- spinnable / knappable / piercing … (open vocabulary)
-- * `composition.*`— material makeup (wood / stone / fiber …)
-- * `weight` — size discriminator (light stick vs heavy branch)
-- * `affordance.*` — functional capability of a TOOL (cutting/hammering/…)
-- e.g. a "haft" = { form="shaft" } → any stick OR branch OR pole works.
-- * `weight` — mass discriminator (light stick vs heavy branch)
-- e.g. a "haft" = { ["affordance.leverage"]=true } → any stick OR branch OR
-- pole works. The SAME affordance vocabulary is required by both consumed
-- `inputs` and non-consumed `tools`; the inputs/tools split (not a separate
-- axis) says whether the item is used up.
--
-- Template-id matching ({ template="rock" }) is ALSO valid — it is just the
-- `form` was RETIRED (ADR-0055 amendment): a physical-shape axis mixed
-- geometry, identity and capability. Its functional members became
-- affordances; its identity members (a "tree") stay template-id.
--
-- Template-id matching ({ template="tree" }) is ALSO valid — it is just the
-- trivial one-property constraint — and is used where a recipe genuinely wants
-- one specific item (see rock_pick/rock_pile in init.lua). Role-based is the
-- default here; template-id is one of the options, not the norm.
-- one specific item (see rock_pick/rock_pile in init.lua, and chop_tree below).
-- Role-based is the default; template-id is one of the options, not the norm.
