REIFY Phase 0.1. Add the end-to-end Phase-0 example: reify a flat enum (value: i64, closed) from a TypeInfo literal, construct E.value(3) / E.closed, and match both arms. Seed an empty expected/*.exit marker. RED by design (reify still bails -> "unparseable expected exit"); the next commit (0.2) implements reify and turns it green. Satisfies the no-commit-both-adds-a-test-and-passes cadence.

// REIFY Phase 0: mint a NEW nominal enum from a `TypeInfo` value at comptime,
|
|
// then construct one of its variants and match on it — exercising that a
|
|
// reify'd enum (with NO backing AST decl) flows through enum codegen unmodified
|
|
// (layout / construct / match), Contract 2.
|
|
//
|
|
// The enum has two variants: `value` carrying an i64 payload, and `closed` with
|
|
// no payload (`payload = void`).
