core: syntax tier — move when to the overlay ahead of the kernel (jolt-1j0 phase 3)

Browse source 
New 00-syntax tier loaded FIRST (before 00-kernel), interpreted defmacros, so the
control macros the compiler and every later tier depend on can live in Clojure.
Validated by moving when: the kernel tier, self-hosted analyzer and seq/coll
tiers all compile against the overlay when. Constraint: syntax-tier macros may use
only special forms + core-renames seed primitives (not second/peek/kernel fns).

conformance 228/228 x3, full suite green.

;; clojure.core — syntax tier. The control macros the compiler and every later
;; tier depend on (when/cond/and/or/...), expressed as defmacro. Loaded FIRST
;; (before 00-kernel), interpreted, so the macros exist before any code that uses
;; them is compiled — including the kernel tier, the self-hosted analyzer, and the
;; seq/coll tiers.
;;
;; CONSTRAINT: a macro here may use ONLY special forms (if/do/let*/fn*/not) and
;; core-renames SEED primitives (first/next/rest/nth/count/empty?/...). It must
;; NOT use kernel-tier fns (second/peek/subvec/...) or anything defined later —
;; those don't exist yet when this tier loads.
