giles	3c419501e1	Fix r7rs.sx: remove guard macro (transpiler blocker), fix null?/boolean=? ... guard macro expansion loops in the transpiled evaluator because expand_macro→eval_expr→CEK can't handle let+first/rest in macro bodies. Removed guard macro; will re-add as special form once transpiler handles runtime AST construction (cons/append/make-symbol). Fixed null? to handle empty lists (not just nil). Fixed boolean=? to use = instead of undefined eq?. 2561/2568 tests pass (37 new vs baseline, 5 guard + 2 scope pending).

giles	d4244b47bf	R7RS compat library + 45-test suite (27 passing, 17 need lib load fix) ... lib/r7rs.sx: guard/with-exception-handler macros, error objects (make-error-object, error-object?, error-message, error-object-irritants), R7RS aliases (car/cdr/cadr/null?/pair?/procedure?/boolean=?/symbol->string/ number->string/string->number), string->symbol. spec/tests/test-r7rs.sx: 9 suites covering call/cc (7), raise (4), guard (5), with-exception-handler (1), error-objects (4), multi-map (6), cond=> (4), do-iteration (4), r7rs-aliases (10). 27/44 pass — the 17 failures need r7rs.sx auto-load in the test runner (currently commented out pending transpiled evaluator hang investigation).
