/**
 * Formula Parser
 *
 * Converts a token stream into an Abstract Syntax Tree (AST).
 * Implements a Pratt parser (top-down operator precedence) for correct
 * handling of operator precedence and associativity.
 *
 * Excel operator precedence (highest to lowest):
 *   1. Unary + / - / %
 *   2. ^  (exponentiation, right-assoc)
 *   3. * /
 *   4. + -
 *   5. &  (concatenation)
 *   6. = <> < > <= >=  (comparison)
