Give a node's input ports a name. PortSpec { kind, firing } is the lone unnamed
member of the node signature today (FieldSpec.name / ParamSpec.name already
exist); a leaf node's input slots have no declared semantics. Add a
non-load-bearing name: String to PortSpec (drops Copy, mirrors ParamSpec), name
every input slot across aura-std nodes + fixtures, carry Role.name into
derive_signature's derived composite port (it is dropped today), and make
model_to_json emit the name in each port tuple. Identity stays positional by
slot (C23); the name is render/debug only, never read by bootstrap or the run
loop.
Surfaced by the 0026 graph-render redesign: a homogeneous pin-graph needs the
name to label input pins instead of inventing "a"/"b". Single iteration.
Design ratified interactively (brainstorm); grounding-check PASS (every
load-bearing current-state assumption ratified by a named green test); parse
gate a no-op (no spec_validation parser configured). Forks resolved: name is a
pure debug symbol, not wire-by-name (C23); String not &'static str (variadic
nodes generate term[i]/col[i]); no bootstrap validation this cycle.
