Class/forName honesty + class/isa? conformance for builtins (#243)
Class/forName claimed every java.*/clojure.* name found (and any "x.y.Class"
matched the registered Class via a short-name fallback), so a library's
(class-found? "optional.Dep") feature-probe always said yes — tools.logging then
tried to build the java.util.logging / log4j backends jolt lacks and crashed.
Resolve forName by exact registry lookup + an honest prefix that excludes the
unbacked optional packages (java.util.logging, javax.management), so the probe
sees them absent and skips the backend.

class of a persistent collection / namespace now reports its JVM class name
(clojure.lang.PersistentHashSet, …Namespace, …) instead of jolt's internal :set/
:object tag, and isa? consults JVM class assignability — Object as every class's
root plus a modeled clojure.lang/java.util hierarchy — so (isa? (class x) C) and a
class-keyed multimethod dispatch like the JVM (e.g. (isa? Keyword Object) was
false). Adds the bare class tokens (Fn/Namespace/Set/…) these dispatch on.

(type x) is unchanged — it keeps jolt's documented internal-keyword form. Six
JVM-certified corpus rows. make test green, 0 new divergences.

instance? matches a thrown :class envelope by its class hierarchy (#242)
A library that throws an ex-info envelope carrying a JVM :class (jolt.host/
tagged-table with a "class" entry — e.g. http-client's UnknownHostException on a
DNS failure) was caught only by a broad (catch Throwable …): (class e) read the
class but (instance? C e) — which catch dispatch lowers to — always returned
false, so clj-http-lite's (catch UnknownHostException e …) for :ignore-unknown-host?
never matched and the condition propagated.

Add an instance? arm matching such an envelope against the carried class or any
ancestor (full name or last segment), and register the common exception hierarchy
(Throwable/Exception/RuntimeException/IOException + the java.net socket/host
exceptions) so (catch IOException e) / (instance? Throwable e) also match. A
non-throwable class (RuntimeException over an IOException, String) stays false.

Fixes http-client's :ignore-unknown-host? test (116/0/0, was 1 error). make test
green, 0 new divergences. Runtime .ss, no re-mint.

Add java.util.Optional (#241)
A value class libraries return from getters (java.time, and the java.net.http
client shim that aws-api's java backend builds on). Statics of/ofNullable/empty,
methods isPresent/isEmpty/get/orElse/orElseGet/ifPresent/toString, value-equal so
(= (Optional/of x) (Optional/of x)). Five JVM-certified corpus rows. Runtime .ss,
no re-mint.

java.time: parse fractional seconds in formatter-based date parsing (#240)
parse-ms ignored sub-second fractions: a formatter parse of
"2020-07-06T10:59:13.417Z" dropped the .417 (and the ISO_OFFSET_DATE_TIME pattern
"…ssXXX" then mis-aligned, reading ".417Z" as the offset). java.time's ISO
formatters accept an optional fractional second, so jolt should too.

After parsing the seconds field, consume an optional .fff from the input (to
millis) when the pattern carries no fraction field — which is how the ISO_*
constants are modeled here (ss, no S). Also handle the S pattern letter for
explicit .SSS patterns. Carry the fraction into the result.

Fixes aws-api shape iso8601 parse (1 FAIL -> 0; cognitect.aws.util/parse-date now
returns the right Date). Two JVM-certified corpus rows. make test green, 0 new
divergences. Runtime .ss — no re-mint.

java.time: complete LocalTime/LocalDate/Year/YearMonth ChronoField coverage (#239)
tick's fields-test walks every ChronoField a temporal supports and reads it,
which crashed on fields jolt didn't implement. Fill the gaps:

- LocalTime: CLOCK_HOUR_OF_DAY (1..24), HOUR_OF_AMPM, CLOCK_HOUR_OF_AMPM,
  MICRO_OF_DAY — both isSupported and getLong.
- LocalDate: the aligned-* group (ALIGNED_DAY_OF_WEEK_IN_MONTH/_YEAR,
  ALIGNED_WEEK_OF_MONTH/_YEAR).
- LocalDateTime field routing now asks which part supports the field instead of a
  hardcoded date list, so a date field never misroutes to the time part (the actual
  cause of "LocalTime has no field ALIGNED_DAY_OF_WEEK_IN_MONTH" — a ZonedDateTime's
  date field fell through to its time).
- Year / YearMonth gain isSupported / get / getLong.

tick api_test 344/0/1 -> 599/0/0. Seven JVM-certified corpus rows. make test green,
0 new divergences. Runtime .ss — no re-mint.

09a9ad8c75 Add bigdec min/max (review follow-up)
Review found (< 1M 2M) worked but (min 1M 2M) threw — incoherent. Wire min/max
the same way as the other ops: value-position jolt-min/jolt-max shims (new in
seq.ss, added to core-value-procs) and call-position via bd-spec/bd-ops ->
jbd-min/jbd-max.

min/max return the original operand by value, not a coerced copy, matching
Clojure: (min 1M 2.0) -> 1M, (max 1M 2.0) -> 2.0, (min 1.50M 2M) -> 1.50M; a tie
keeps the second operand ((max 1.5M 1.50M) -> 1.50M). bigdec mixed with a flonum
in call position stays in the documented :any/contagion gap (value position
handles it). Re-mint; 6 more JVM-certified rows.

6fcc9fa8e6 BigDecimal call-position arithmetic via :bigdec type (Phase 2)
A direct (+ 1.5M 2.5M) emits a raw Chez + that rejects the bigdec record. Rather
than guard every arithmetic call site (measured 2-4x on unhinted fixnum loops),
let the analyzer dispatch where it can prove the type.

jolt.passes.numeric seeds a :bigdec kind from the M-literal and flows it through
let/loop/if like the existing :double/:long kinds; an arithmetic/comparison invoke
whose operands are all bigdec (integer literals allowed) gets :num-kind :bigdec.
The back end (bd-ops + emit-numeric) lowers those to the bigdec.ss engine
(jbd-add/-sub/-mul/-div, jbd-lt?/…, jbd-zero?/-pos?/-neg?, jbd-quot/-rem).

Zero cost on non-bigdec code: with no bigdec literals present the kind never
arises, so emission is byte-identical — the re-mint leaves prelude.ss unchanged,
only image.ss (the compiler) moves. Gaps (filed): a bigdec mixed with a flonum in
call position, and a bigdec the analyzer types :any, still hit the raw op and
throw; use value position or a literal-typed let.

Re-mint (numeric/backend are seed sources). 16 JVM-certified corpus rows.

bd7b75fb5d BigDecimal arithmetic: value-position + compare (Phase 1)
bigdec values existed but +,-,*,/ and compare threw — the header even said
"arithmetic contagion is not modelled". Add the scale-aware engine on the
{unscaled, scale} pair (jbd-add/-sub/-mul/-div + comparison helpers) following
java.math.BigDecimal's rules: add/sub align to the larger scale, multiply adds
scales, divide gives the exact quotient at minimal scale or throws
ArithmeticException on a non-terminating expansion. Clojure contagion: a bigdec
mixed with an integer stays bigdec, a flonum operand wins (result is a double).

Wire it into the value-position shims only — jolt-add/-sub/-mul/-div (what
(reduce + bigs)/(apply * bigs) lower to) and compare — so the inlined native hot
path is untouched. A call-position (+ 1.5M 2.5M) still reaches the raw Chez op;
that needs the analyzer's :bigdec type (next).

Runtime .ss only, no re-mint. 13 JVM-certified corpus rows.

ec9fde9e7e Group the JVM interop shims under host/chez/java/
The host/chez directory mixed jolt's own runtime (value model, seq, reader,
vars, ns, multimethods) with the shims that emulate the JVM: java.* / javax.*
classes, clojure.lang interfaces, and the host-class registry they hang off.
Move that JVM-emulation layer into host/chez/java/ so it reads as a distinct
unit instead of being interleaved with the platform runtime.

Moved (content unchanged): host-static, host-static-methods,
host-static-classes, host-class, dot-forms, records-interop, byte-buffer,
io, io-streams, inst-time, java-time, bigdec, natives-queue, natives-str,
natives-array, math, concurrency, async, ffi.

The load paths in rt.ss/cli.ss and the build.ss runtime manifest are updated
to point at java/; the build inliner follows the (load ...) strings, so the
AOT path needs no other change. All runtime shims, no seed source touched
(the three .clj edits are doc comments), so no re-mint.

Gate green: make test (selfhost fixpoint, certify 0-new, sci 211, infer),
shakesmoke (4 apps byte-identical).
