giles 2e7e3141d4 reflective: extract env.sx + migrate Kernel — 322 tests green ...

Phase 1 of the lib-guest-reflective extraction plan.

lib/guest/reflective/env.sx — canonical wire shape
{:refl-tag :env :bindings DICT :parent ENV-OR-NIL} with mutable
defaults (dict-set!), plus *-with adapter-cfg variants for consumers
with their own shape (modelled after lib/guest/match.sx). 13 forms,
~5 KB.

lib/kernel/eval.sx — env block collapses from ~30 lines to 6 thin
wrappers (kernel-env? = refl-env?, etc.). No semantic change; envs
now carry :refl-tag :env instead of :knl-tag :env. All 322 Kernel
tests pass unchanged across 7 suites (parse 62, eval 36, vau 38,
standard 127, encap 19, hygiene 26, metacircular 14).

Next: Phase 2 — Tcl adapter cfg in lib/tcl/runtime.sx using
refl-env-lookup-with against the existing :level/:locals/:parent
frame shape.
