72e36f46de test+docs: spec coverage for migratus-enablement fixes; list migratus
Adds spec/conformance coverage for everything landed enabling migratus:
- conformance corpus (runs interpret/compile/self-host): def 3-arg docstring,
  def/defn ^{:map} name meta, defmacro arity-clause + docstring, defmulti
  docstring, assoc-nil/assoc-in real maps, try multi-body + finally-on-success,
  current-ns restore after a caught throw, cross-ns methods visibility.
- spec suites: host-interop (exception ctors, Character/Thread/Long, Timestamp/
  SimpleDateFormat, java.io.File model + File-aware file-seq, clojure.tools.logging),
  regex (Pattern statics + MULTILINE + quote, String .matches/.replaceAll/
  .replaceFirst), maps (assoc on nil), multimethods (defmulti docstring +
  value-based methods/get-method), macros (defmacro arity-clause + name meta).

Rewrote clojure.tools.logging/spy as a single variadic arity (jolt defmacro
takes only the first clause of a multi-arity macro — jolt-q8l).

docs/libraries.md: add migratus and the next.jdbc compatibility layer, with the
janet-lang/sqlite3 int64 caveat for 14-digit timestamp ids.

Full gate green; conformance 350/350 x3 modes.

63eb6eca6e core: staged recompile for early defns; keys/vals/empty? leave the seed (jolt-4j3)
recompile-defns! is the defn analog of recompile-macros!: pre/at-kernel
overlay defns (00-syntax's destructure and friends; the kernel tier too in
interpret mode) load as interpreted closures, the evaluator stashes their fn
source on the var (:defn-src, scoped by a flag only api/load-core-overlay!
sets), and the end-of-init pass compiles them and swaps the var root. With
that in place, keys/vals/empty? — the fns the 00-syntax expanders call at
expansion time — move to the top of 00-syntax as raw fn* defs (canonical:
keys/vals project (seq m), so sorted maps come back in comparator order and
(keys {}) is nil; empty? keeps O(1) count dispatch with seq's cell check only
for the lazy/list fallback). The sorted tier drops its now-dead :keys/:vals
ops.

Correctness fixes that surfaced once the gate was run with a REAL exit code
(the previous 'jpm test | grep' gates reported grep's exit and masked spec
failures across #48-#50):
- map conj is strict again: a non-nil/non-map arg must be a 2-element vector
  ('Vector arg to map conj must be a pair'), and merge inherits it — the
  batch-2 canonical merge had silently dropped the validation
- conj onto a lazy seq prepends (it fell into the MAP fallback); upstream
  clojure.data/diff relies on (conj seq x) via set/union over keys, so diff
  now matches Clojure exactly
- (seq {}) / (seq #{}) / empty phm are nil, not ()
- key/val are strict (a plain vector is not an entry); find mints a REAL
  entry as the first entry of a one-entry map, nil values intact
- the sci avoid-method-too-large stub passes its registry map through
  instead of returning a raw host table (strict conj rejected it; sci's
  clojure-core registry is also no longer discarded)

Test updates: lazy-infinite pins take-nth realization at 5 (was 7 — the
canonical lazy impl realizes fewer); self-host asserts the analyzer IS loaded
in interpret mode (compiled expanders, PR #50) and is NOT in the
:compile-macros? false oracle. 18 new maps-spec rows.

Gate: jpm test exit 0 (verified directly, not through a pipe), conformance
326x3, suite 4698 >= 4660.

eb7a9f1b20 core: spec 35-var batch A — 1.11 parsers, map/partition variants, with-redefs, ns fns
Fifteen vars from the spec coverage gap (docs/spec/coverage.md):
parse-long/parse-double/parse-boolean (strict validation; scan-number alone
accepts 0x10), newline, current-time-ms (host clock for time), update-keys/
update-vals (PHM base, collisions last-wins), partitionv/partitionv-all/
splitv-at (lazy seqs of vectors; splitv-at's tail stays a seq, matching the
reference), with-redefs/with-redefs-fn (roots restored on throw), time,
macroexpand (expand-1 to fixpoint), alias/ns-unalias (write BOTH alias stores
— require :as uses string-keyed :imports while ns-aliases reads :aliases;
split filed), ns-publics (symbol-keyed map; publics == interns, no privacy).

Three pre-existing bugs fixed along the way:
- (partition n step pad coll) misparsed pad as the coll and returned ()
- (require 'bare.symbol) rejected — only vector specs were accepted
- analyze-form leaked the interpreted analyzer's ns on a punt: a throw out of
  the analyzer left current-ns=jolt.analyzer and :compile-ns set, so the
  fallback interpretation resolved user vars against the wrong namespace
  (bit (var user-sym) under compile mode)

And one overlay-authoring landmine documented in-code: a 20-coll fn must not
use 30-macros macros (with-redefs-fn's dotimes compiled as a forward ref that
resolved to the macro fn at runtime) — loop/recur instead.

Gate: conformance 316x3 (+14 rows), suite 4324 pass / 78 clean (was 4081/72;
parse_*/update_* files now contribute), baselines raised, all specs+unit,
fixpoint, self-host, sci, staged. Coverage: missing-portable 35 -> 20.

Compiler research (#10)
adds self-hosted compiler is functionally:
 
- The default compile path is the portable pipeline using jolt.analyzer (Clojure) → host-neutral IR → backend.janet.
- The analyzer is itself Clojure, compiled by jolt for true self-hosting.
- bootstrap-fixpoint passes (stage1 == stage2 == stage3): rebuilding the compiler on its own output.
- clojure.core is now self-hosted in the overlay.
- Stateful forms (defmacro/ns/deftype/defmulti/require/in-ns) are interpreted by design.

360b23c8af feat: distinguish map entries from vectors; min-key NaN ordering; subvec float coercion
- A map entry is a 2-element tuple (Jolt produces tuples only from map iteration;
  vector literals are pvecs, lists are arrays). key/val/map-entry? now accept a
  2-tuple and reject a plain vector, matching Clojure's MapEntry-vs-vector
  distinction — no metadata needed, the representations already differ.
- min-key/max-key reproduce Clojure's NaN-aware folding (2-arg strict </>, then
  <=/>=) and require numeric keys (NaN allowed, strings throw).
- subvec coerces float/NaN indices like (int ...) (truncate, NaN->0) then
  bounds-checks, instead of throwing on non-integers.

min_key 35/14 -> 49/0 (clean); key/val recover the 2-vector cases; subvec floats
fixed. clojure-test-suite pass 3898->3921. Updated conformance-test (key/val now
needs a real entry). spec: map/map-entry-&-key-ordering (14). jpm test green.

f644b4b719 feat(strictness): merge rejects atomic/wrong-shape args into a map
merge now throws when a non-first arg is a scalar, a set, a list, or a
wrong-length vector (a length-2 vector or a map still merge). Other map-like
tables (records/sorted-maps/host tables, e.g. SCI's namespaces) keep the lenient
conj path so the SCI bootstrap still loads.

merge 29/11/2 -> 35/3/4. clojure-test-suite pass 3874->3880.
spec: 5 merge strictness cases. jpm test green.

ff3cc7d6c0 feat(strictness): assoc bounds, dissoc/count map-only, subvec bounds, numerator/denominator, min-key empty
- assoc on a vector bounds-checks the index (0..count); out-of-range/negative throw
- dissoc throws on non-maps (numbers/sequences/sets/scalars); nil ok; records/
  sorted-maps/meta-maps still handled
- count throws on scalars (numbers/keywords/symbols/booleans/chars)
- subvec validates vector type and 0<=start<=end<=count
- numerator/denominator always throw (Jolt has no ratio type)
- min-key/max-key throw on no values

count 18/2; dissoc 19/3; assoc 36/6; subvec 26/3/5; numerator/denominator throw
cases pass. clojure-test-suite pass 3840->3864. spec: map/strictness (16). jpm test green.

e75771084e fix: merge nil/empty + conj semantics to match Clojure
core-merge returned {} for (merge) and errored on nil args. Rewrite to follow
Clojure: (when (some identity maps) (reduce conj (or (first maps) {}) (rest maps))).

- (merge) and (merge nil nil) -> nil
- nil args elsewhere are no-ops: (merge {} nil) -> {}, (merge nil {:a 1}) -> {:a 1}
- later args follow conj semantics: a map merges its entries, a [k v]
  vector/map-entry adds that entry ((merge {} [:foo 1]) -> {:foo 1},
  (merge {} (first {:a 1})) -> {:a 1})
- collection keys preserved (first arg's phm type kept; entries via core-assoc
  which promotes struct->phm for collection keys)

spec: 9 new merge cases in maps-spec. merge.cljc 13/18/11 -> 29/11/2.
clojure-test-suite pass 1688->1704. jpm test green.

Remaining merge.cljc fails are the lenient-where-Clojure-throws class (atomic
args, >2-element vectors). Fixes jolt-dxx.

0db7eb6ac8 fix: value-semantics for collection keys/elements; set literals evaluate
Close jolt-do7. Maps/sets keyed by a collection (a map, vector, ...) now compare
by value instead of Janet identity:
- PHM/PHS hash and compare keys through an injected canonicalizer (collection
  keys -> value-hashable struct/tuple); keys are still stored as-is
- map literals and core-assoc promote to a phm when a key is a collection
- frequencies/group-by use a phm base so collection elements/keys dedup by value
- set equality is value-based (from earlier)

Real bugs found and fixed along the way:
- set literals #{(inc 1)} did not evaluate their elements (stored raw forms!)
- the REPL printer rendered phm maps as {} (they hit the deftype branch); now a
  phm branch prints entries

Added spec cases (maps/collection-keys, sets/literals & value elements).
conformance 218/218, jpm test green.

b353d625f1 test(spec): collections contract (sequences, vectors, lists, maps, sets)
Add behavioral spec suites for the collection API (~180 cases). Writing them
surfaced and fixed real bugs:
- (count nil) errored; now 0 (Clojure semantics)
- (repeat x) and (repeatedly f) — the infinite 1-arg arities — were unsupported;
  now return lazy infinite seqs
- set equality used deep= (representation-sensitive), so a set of map literals
  could differ from an equal set built differently; now value-based (each
  element value-equal to some element of the other)

Known limitation filed: phm-typed maps (from hash-map) used as set elements /
map keys hash by identity (map *literals* are structs and work).

jpm test green.
