101 aspire comptime data to liquid

// ASPIRATION — currently RED, a PIN not a regression (never been green).
//
// THE DATA→LIQUID BRIDGE (named 2026-07-04): comptime Koru computes a VALUE;
// that value crosses into a template's Liquid context as DATA — completing
// the loop comptime-Koru → data → Liquid → Koru source → parsed AST.
//
// Today this is impossible twice over:
// 1. PHASE ORDER: templates render in elaborate (process-template-procs)
//    BEFORE comptime evaluation (fold-comptime/evaluate-comptime), so a
//    template arg fed from a comptime binding receives raw call-site TEXT
//    ("v"), never the evaluated value.
// 2. MARSHALLING: the Liquid context is built only by the compiler from the
//    invocation node — there is no channel from interpreter Values into
//    template data. Scalars here; the same bridge carries arrays/cells for
//    `{% for %}` iteration (the tier that dissolves 310_100's invented
//    order_by_hits filter: comptime Koru computes the order, Liquid just
//    renders it).
//
// Grounded surface: comptime event/impl/bind mirrors 310_098 (green); arg
// passing from a binding mirrors green branch-arg shapes; the |koru facet
// and [template] head are the 310_099 aspiration. ASPIRATIONAL bit unique
// to THIS pin: a comptime-evaluated value arriving in Liquid as data.
