java.time DST + data readers: make tick pass fully

Shaking out tick's api and alpha.interval suites (api 353->359, interval
0->103 passing) cleared a set of general gaps:

- Named-zone DST. Zones resolved to a fixed representative offset, so
  America/New_York in August read -05:00 not -04:00. Add US/EU DST rules
  (compact transition-date math) and make instant<->zoned, the zone rules'
  getOffset, and the zoned equality arm DST-aware.

- Nanosecond zoned/offset times. Instant is nanos but atZone/atOffset/
  toInstant/withZoneSameInstant and Instant/parse went through epoch-ms,
  truncating sub-ms. Route them through nanos.

- Locale month/day names. A formatter dropped its Locale; carry it and add
  French names so MMM under Locale/FRENCH renders "mai".

- Callable records. A defrecord implementing clojure.lang.IFn (tick's
  GeneralRelation) is now invokable: jolt-invoke dispatches to its inline
  invoke method. Also give collections the Iterable host tag so a protocol
  extended to Iterable matches vectors/seqs.

- Imported class short names. (:import [java.time ZonedDateTime]) then
  (. ZonedDateTime parse s) resolved to nil; an otherwise-unresolved bare
  Capitalized name that's a registered host class now resolves as a class.

- Data readers. A project's data_readers.{clj,cljc} is loaded into
  *data-readers* (reader namespaces required eagerly); registered #tag
  literals in source rewrite to (reader-fn 'form). clojure.core/read-string
  now applies #inst/#uuid/#"regex" and *data-readers* like Clojure.

- Duration/between accepts zoned/offset date-times.

All runtime shims, no re-mint. docs/libraries.md: tick full pass + aero.
