edn: port read-string onto the reader; fix special-form ns shadowing

Browse source 
clojure.edn/read-string now delegates to clojure.core/read-string (the
reader-based special form — parses, never evals) via a private helper, with the
opts-map :eof arity and nil/blank-input handling. 43 -> 47 in the stdlib battery.

This required an evaluator fix: special forms were matched by name only, so
clojure.edn/read-string dispatched the core read-string SPECIAL FORM instead of
the var. Now a head qualified to a non-core namespace resolves to its var; only
unqualified or clojure.core-qualified heads are special forms. Conformance
218/218 all modes; full suite green.

Remaining edn gaps (jolt-b7y): set literals read as a set FORM not a constructed
set, and #uuid has no real type.
