General fixes shaken out by running core.logic's test suite

Running clojure/core.logic's own suite surfaced a batch of general jolt gaps.
None are core.logic-specific; each is a language/host behavior that was wrong or
missing. With these, the core relational engine (unify, run/fresh/conde,
conso/membero/appendo, reification to _0/_1, lcons) runs; the remaining failures
are in core.logic's constraint-logic-programming and finite-domain layers
(tracked separately).

- analyzer: accept the list-member dot form (. target (method args)), sugar for
  (. target method args). Re-mint.
- identical? is reference identity (eq?), not value equality. It was aliased to =,
  which infinite-loops when a deftype's .equals short-circuits on (identical? this o)
  (core.logic's Substitutions) and is wrong for distinct equal collections.
- jrecs use a deftype's declared hashCode/equals/equiv for map/set keying instead
  of structural field comparison, so metadata-wrapped keys still match (core.logic
  keys substitutions on lvar id, ignoring metadata).
- meta/with-meta dispatch to a deftype's clojure.lang.IObj meta/withMeta methods
  when present, so metadata threaded through the type's own assoc/withMeta survives
  (previously kept in an identity side-table the reconstructed instances didn't share).
- coll?/seqable? on a deftype require IPersistentCollection (cons) or ISeq (first);
  ILookup(valAt)/Indexed(nth)/Counted(count)/Seqable(seq) alone no longer qualify,
  matching the JVM.
- syntax-quote resolves a bare symbol to the compile ns's own def before
  clojure.core, so a name the ns excluded and redefined (core.logic's == after
  :refer-clojure :exclude) qualifies correctly in macro output.
- reader: record literals #ns.Type{...} / #ns.Type[...] expand to the map->/->
  factory call.
- structmap API: defstruct/create-struct/struct-map/struct/accessor (map-backed,
  insertion-ordered). Re-mint.
- .hashCode on strings/symbols (Java String.hashCode, Symbol Util.hashCombine);
  Class.isInstance; java.util.Collection.contains over vector/list/set;
  clojure.lang.RT/nextID and clojure.lang.Util hash/hasheq/equiv/identical statics.

corpus.edn: 8 JVM-certified rows. unit.edn: a Counted+Seqable deftype is coll?=false
(was a stale expectation encoding the old behavior).
