Comprehensive spec (#19)
* core: fix jolt-265 — syntax-quote fully-qualifies core syms to clojure.core/

Re-attempt of the deferred gap, now unblocked. The earlier uberscript break
wasn't qualification itself but an aliased-ref resolution bug it exposed:
resolve-var looked up ns-aliases (e.g. g/foo) against the analyzer's REBOUND
ctx-current-ns (jolt.analyzer, since the analyzer runs interpreted in its own
ns) instead of the namespace being compiled. A user's aliased refs failed
mid-compile (g/hello -> nil in the bundled standalone).

- resolve-var resolves aliases against :compile-ns when set (same ns
  h-current-ns uses), falling back to ctx-current-ns — correct for both modes.
- sq-symbol qualifies a resolved clojure.core name to clojure.core/<name>
  (Clojure hygiene); special forms stay bare; unresolved syms -> current ns.

Tests updated to the qualified behavior (features-test, reader-forms-spec).

* test: comprehensive spec — regex + sorted colls + random/predicate gaps

Filling the biggest untested clojure.core areas found in a coverage audit
(168 of 506 provided fns had no spec). New + expanded suites:

- regex-spec.janet (20): #"…" literals, regex?, re-find/re-matches/re-seq
  (match/no-match/groups), re-pattern, and clojure.string split/replace with
  regex (incl $1 backrefs). Whole area was previously unspecced.
- sorted-spec.janet (14): sorted-map/sorted-set construction + ordering, sorted?,
  subseq/rsubseq. Pins the working subset — get/conj/assoc/keys/vals on sorted
  colls and the by-comparator ctors are not yet first-class (jolt-ti9).
- predicates-spec +14: seqable?, integer?, reduced?/unreduced, not-empty.
- numbers-spec +5: rand/rand-int/rand-nth invariants.

Fix: sorted? was bound to core-sorted-map? so it returned false for sorted-sets;
now true for both sorted maps and sets (core-sorted?).

Filed: jolt-ti9 (sorted collections incomplete: get/conj/assoc/keys/vals don't
operate on the sorted wrapper; sorted-*-by ignore the comparator).

Gate green incl full jpm build + jpm test.

* core: close surfaced gaps — first-class sorted colls, with-out-str, rand arity, deref reduced

jolt-ti9: sorted-map/sorted-set are now first-class across the collection fns —
get/assoc/dissoc/conj/contains?/keys/vals/disj and call-as-fn all operate on the
wrapper and preserve sort order. The by-comparator constructors (sorted-map-by/
sorted-set-by) now thread the user comparator (numeric or boolean-predicate) through
all derived colls. Sorted predicates/ctors/ops moved above core-conj so the
collection fns can branch on them; jolt-invoke (interpreter) gets inline branches.

jolt-rfw: add with-out-str (binds output to a string buffer) + the macro.
jolt-ek3: (rand n) arity and deref-of-reduced (uuid? still deferred).

Specs: new io-spec.janet; sorted-spec expanded to pin the now-working map/set ops
and by-comparator ordering; predicate/number spec restorations.

* remove old doc

* core: fix stale comment — by-comparator sorted ctors are implemented
