Adds the missing tilde operator '~' (Go 1.18+ generics type-set
constraint, e.g. 'interface { ~int | ~float64 }') to the longest-match
operator table. Adds an exhaustive 'op-audit:' test block covering
every Go operator/punctuation token by category — arithmetic +
assignment, bitwise + assignment, comparison + logical, decls /
arrows / variadic / inc-dec, punctuation, and tilde.
Phase 1 (tokenizer) is now complete. Two kit gaps surfaced and logged
in plans/go-on-sx.md Blockers for the substrate maintainer / next
statically-typed guest loop:
* lib/guest/lex.sx lacks lex-oct-digit? / lex-bin-digit?
(we rolled local gl-* equivalents for 0o.. and 0b.. literals).
* lib/guest/lex.sx lacks a table-driven longest-prefix operator
matcher; our gl-match-op is a 25-clause cond ladder. Rust/Swift/TS
will each hit the same shape with 50+ ops apiece.
lex 129/129. Phase 2 (parser) next.
