lib/guest/prefix.sx defines a single (defmacro prefix-rename PREFIX ENTRIES)
form that takes a prefix string and a quoted list of entries. Each entry
is either a bare symbol (same-name alias: cl-foo = foo) or a 2-element
list (alias target) for renames (cl-mod = modulo).
Ported lib/common-lisp/runtime.sx: 47 hand-written (define cl-X Y) lines
across 13 contiguous groups now collapse into prefix-rename calls. Loaded
lib/guest/prefix.sx in the conformance preamble so the macro is available
when runtime.sx is parsed.
Verification: cl scoreboard 518/518, up from a stale baseline of 309/309
— Phase 2 (evaluator, +182) and Phase 6 (stdlib, +27) had under-counted
historical results, not affected by this change. No regressions; baseline
updated to reflect true counts.
PARTIAL — pending second consumer. lua/runtime.sx (the brief's specified
second consumer) has zero pure same-name aliases — every lua- definition
wraps custom logic. Step left [partial — pending lua] until a consumer
fits, or the second-consumer choice is revisited (js/runtime.sx has 2
candidates: isFinite/isNaN).

FORMAT with ~A/~S/~D/~F/~%/~&/~T/~P/~{...~}/~^; cl-fmt-loop,
cl-fmt-find-close, cl-fmt-iterate, cl-fmt-a/cl-fmt-s helpers.
Fix substr(start,length) semantics throughout: SUBSEQ end formula
corrected to (- end start), cl-fmt-loop char extraction fixed.

defmacro/macrolet/symbol-macrolet/macroexpand, gensym/gentemp, full
LOOP macro (loop.sx) with all clause types. Phase 2 dynamic variables:
cl-apply-dyn, cl-letstar-bind, cl-mark-special!/cl-special? for
defvar/defparameter specials with let-based dynamic rebinding.
27 macro+LOOP tests; 182 eval tests (8 new dynamic var tests).
