Daniel Covington aa60ee11e0 newLang: add the expression and statement parser (E03-S03) parse_statement parses every spec 7 form (assignment, call, if/else, while, for/to/step, return, print, delete) and requires the line to end after it. Expressions use precedence climbing over spec 8's levels: binary operators left associative, unary not and - nesting rightwards, postfix member access, calls, and indexing tightest. A syntax error is reported in pass 1, unwinds to the statement, and skips the line; E03-S02's name, member, and access checks now run from the parser in pass 2, replacing the token scan. Expression nesting is bounded at 16 levels (E225). Verified in x128: 31 fixtures, including the two statement fixtures that were pending since E03-S01, a postfix trace golden for precedence and associativity (both mutations caught), every statement form, and 15 independent syntax errors with recovery. Lowest stack pointer $A7. New diagnostics E038-E042 and E225. The demo passes; its Vim typing is slowed to 200 ms per key after one doubled keystroke.
