059 wire parse accepts one invocation

// Pins the wire grammar's accept side: `std/runtime:parse.wire` takes a turn
// exactly as a model emits it — one `verb(field: "value")` invocation, quoted
// string values, nothing else — and hands back a parsed flow. The restricted
// channel accepts what the register block can dispatch; the escape hatch is
// closed on the other side (430_060..430_062 pin the refusals).
