fix: Phase 5 — MEDIUM #27,30,31 + LOW #25,41 complete cleanup

Files modified (6): compiler/parser/parser.go — #27: Add currentUpper() helper Replaces 30 strings.ToUpper(p.current.Literal) calls compiler/parser/stmtreg.go — Remove now-unused strings import compiler/parser/expr.go — #30: Document comma expr Harbour semantics compiler/gengo/gengo.go — #31: Replace 8 TODO comments with WARN Macro expr now emits MacroPush() instead of TODO compiler/token/token.go — #25: Replace itoa with strconv.Itoa #41: Add 50+ missing kindNames entries for complete String() Issues resolved: #25,27,30,31,41 Total fixed: 39/53 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
