Updates Phase 7 status:
- env.sx ✓ extracted (three live consumers: Kernel, Tcl, Smalltalk,
with Scheme also using it directly)
- class-chain.sx ✓ extracted (bonus — not on the original six-file
list but surfaced by the same chiselling discipline; Smalltalk +
CLOS consumers)
- quoting.sx ✓ extracted (Kernel + Scheme consumers)
- evaluator.sx DECLINED — too thin to be its own kit; the shared
content is protocol/API surface, not algorithm. Documented
in-plan, no file created.
- combiner.sx, short-circuit.sx — still need fexpr-having
second consumers
- hygiene.sx — still awaits Scheme Phase 6c (research-grade
scope-set work)
Three kits live, one declined, three still gated.
