Yogthos 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.

Clojure libraries known to work with Jolt

Libraries confirmed to load and pass their conformance checks on Jolt (see test/integration/deps-conformance-test.janet and the ring-app example).

  • config
  • Selmer
  • medley
  • cuerdas
  • ring-core — via :deps/root "ring-core", on the ring-app example's spork/http adapter
  • ring-codec
  • reitit-core — data-driven routing; the reitit.Trie Java class is mirrored in Clojure by jolt-lang/router. Load with JOLT_FEATURES including clj.
  • honeysql — full formatter + helpers (select/insert/update/delete/joins/:inline), loaded unmodified from git
  • clojure.jdbc — as jolt-lang/db's jdbc.core, reimplemented over janet sqlite3/pq drivers (SQLite + PostgreSQL)
  • next.jdbc — a compatibility layer in jolt-lang/db (next.jdbc, next.jdbc.sql, next.jdbc.prepare, next.jdbc.transaction) over jdbc.core, for libraries that target the next.jdbc API
  • migratus — database migrations; loads unmodified and runs filesystem SQL/EDN migrations against SQLite through the next.jdbc layer above. migrate/rollback round-trip end to end. Caveat: migration ids are 14-digit timestamps, and the janet-lang/sqlite3 driver currently truncates INTEGER columns to 32 bits, so completion tracking needs the one-line upstream fix (sqlite3_column_int64); ids under 2^31 work as is.
