core.match: regex + array patterns (full support); library-conformance directive

Finishes core.match — its full test suite (115/115) now passes, including the
two patterns the earlier work left out:

- Regex-literal patterns. A #"…" now reads as a regex VALUE (Clojure parity: the
  reader constructs the Pattern, so a macro receives a regex, not jolt's tagged
  form), and the analyzer compiles a regex value to the same :regex IR leaf via
  its source. emit-quoted handles a quoted regex; a regex value carries the
  java.util.regex.Pattern host tag so extend-protocol/instance? dispatch on it.
- Primitive-array patterns. A ^Type hint's :tag is now the SYMBOL (e.g. `ints`),
  matching the JVM, so core.match's array-tag lookup engages the array
  specialization (alength/aget). jolt's :tag consumers already tolerate a symbol
  (hc-cell-num-ret normalizes; tag->nkind/def-meta handle both).

Also: a library-conformance directive in CLAUDE.md, and the supported-libraries
list (docs + site) simplified to one-line entries — a listed library is assumed
to work fully, so no tallies or feature enumerations. core.match + transit-jolt
added to the list.

Seed change (reader/backend/30-macros) -> re-minted; the rest runtime. JVM-
certified corpus rows; the stale `symbol hint -> :tag` divergence is dropped from
the allowlist (jolt now matches the JVM). make test + shakesmoke green.
