Starts Phase 2. lib/go/parse.sx defines:
* go-precedence-table — Go's five operator-precedence levels in the
(NAME PREC ASSOC) entry shape from lib/guest/pratt.sx, ready for the
binary-operator iteration to consume via pratt-op-lookup.
* go-parse(src) — tokenises and parses ONE primary expression: int,
float, imag, string, rune literals become (ast-literal VALUE);
identifiers become (ast-var NAME). Built directly on lib/guest/ast.sx
constructors — no intermediate AST shape.
Conformance.sh extended to load lib/guest/{ast,pratt}.sx and run the
new parse suite. Scoreboard cleanup: drop the "pending" parse row since
the suite is now real.
parse 17/17 (lex still 129/129). Total 146/146.

First Go-on-SX iteration. Tokenizer consumes lib/guest/lex.sx character-class
predicates. Automatic semicolon insertion per Go spec § Semicolons fires on
newline, EOF, and block comments containing a newline, after
ident/int/string/rune/{break,continue,fallthrough,return}/{++,--,),],}}.
Scoreboard + conformance.sh wired; lex 78/78. Plan Phase 1 sub-items
checked; floats/raw-strings/hex-ints still ⬜.
