java.time Phase 3: zones, offsets, ZonedDateTime, formatters — tick runs

Browse source 
ZoneOffset/ZoneId (SHORT_IDS, fixed-offset + UTC + system; named zones via a
fixed-offset table), ZonedDateTime/OffsetDateTime/OffsetTime, Clock (fixed/
system, with now [clock] arity), and DateTimeFormatter integration (ofPattern
+ ISO_* constants, .format/.parse over the rich java.time values via the
inst-time.ss pattern engine). systemDefault resolves to UTC to keep the
#inst atZone/toInstant round-trip machine-tz-independent.

tick.core + tick.protocols + tick.locale-en-us load; tick's api_test runs
31 tests / 352 pass / 7 fail / 0 error. The 7 are host gaps: named-zone DST
(no tzdb), French locale month names (no locale DB), nanosecond Instant.

General fixes surfaced by tick: :ns/keys map destructuring ({:tick/keys [..]})
in 00-syntax.clj (re-minted), and extend-protocol to java.time classes
(records.ss host-type-set). 12 corpus rows certified vs JVM. make test +
shakesmoke green, selfhost holds, 0 new divergences, data.json stays 138/139.
