go: eval.sx scaffold — literals + vars + binops + 25 tests; Phase 3 closed [nothing]
Phase 3 — bidirectional type checker — is fully ticked (short-decl
was already implemented). Phase 4 starts here.

lib/go/eval.sx single judgment:

  (go-eval ENV EXPR)  →  VALUE | (list :eval-error TAG ...)

ENV is an association list of (NAME VALUE) bindings — same shape as
the type checker's ctx, but the entries are runtime values. Values
are represented directly in SX: integers/floats as SX numbers,
strings as SX strings, booleans as true/false, nil as nil. Composite
values (slices/maps/structs/pointers/channels) arrive in later slices.

First-slice coverage:

  * go-env-empty / -lookup / -extend
  * Literal decoding:
      decimal (with underscores)
      hex (0x.. / 0X..)
      oct (0o.. / 0O..)
      bin (0b.. / 0B..)
    via go-hex-digit-value (explicit char equality — SX's nth on
    strings returns single-char strings, not numeric codes; the
    arithmetic-on-char-codes pattern from the OCaml kernel ports
    doesn't work here).
  * Identifier lookup with predeclared true / false / nil.
  * Binops: + - * / and the six comparison ops and && / ||.
  * Errors as (:eval-error TAG ...) sentinels.

Statements (block / return / short-decl / assign), control flow
(if / for), and function application / closures arrive in subsequent
slices.

eval 25/25, total 402/402.
