  compiler/token/token.go — #25: Replace hand-rolled itoa with strconv.Itoa
    Fixes math.MinInt overflow bug in original implementation
  compiler/ast/ast.go — #29: Fix VarDecl.End() returning last var position
    Was returning Pos() (useless span info)
  compiler/parser/stmtreg.go — #28: Eliminate all 7 token array mutations
    rewriteAsIdent() modifies p.current only, not the token array
    Prevents backtracking corruption and improves safety
  compiler/lexer/lexer.go — Already clean from Phase 2
