Yogthos df1e836cda Phase 13: Protocol Completion — reify dispatch, #() reader, IFn protocol
- reader.janet: rewrite read-anon-fn to handle % arg references
  % → gensym, %1/%2 → sorted gensyms, replaces all matching % refs
- evaluator.janet: IFn protocol support in default invocation arm
  Before erroring "Cannot call X as a function", checks for:
  1) type-registry IFn/-invoke method (extend-type protocols)
  2) :jolt/protocol-methods :-invoke (reified objects)
- test/phase13-test.janet: 4 test sections (28-31)
  28: reify dispatch — protocol methods on reified objects
  29: #() anon-fn — % and %1/%2 arg handling
  30: extend-type — protocol method dispatch for deftypes
  31: clojure.walk loading — keywordize-keys loads correctly
- All pass: 316 ok, 1 fail (pre-existing, unchanged)

REPL print-value uses buffer-based output: write-value/v buf appends formatted strings via buffer/push-string, then print-value creates buffer, builds string, and does a single (print (string buf)). This prevents Janet C runtime from interleaving native <tuple 0x...> output between prin statements in jpm build executables. Cond catch-all must use true clause: Janet's cond treats plain expressions as tests, so (push-str buf (string v)) at end of cond would be evaluated as a test — need true before it. § Post-Phase 11: 316 passing, 1 fail (pre-existing array/table/buffer in SCI lang.cljc, deferred to Phase 15). 7,800+ lines across ~20 source/test files. 9 .clj stdlib modules (clojure/string.clj, set.clj, walk.clj, zip.clj, edn.clj, java_io.clj; jolt/interop.clj, shell.clj, http.clj). 85 CLJS-ported assertions. SCI stub file at src/jolt/clojure/sci/lang_stubs.clj provides 5 protocols + 3 deftypes. 24 test files. All builds/runs via jpm test. § Project stats after Phase 12: 7,800+ lines across 30+ source/test files. Key sources: compiler.janet (848 lines), evaluator.janet (869 lines), core.janet (1387 lines), types.janet (441 lines), reader.janet (472 lines), phm.janet (199 lines), main.janet (125 lines), api.janet (93 lines), loader.janet (79 lines). Test suite: 316 ok, 1 fail (pre-existing deftype in lang.cljc). 17 CLJS-ported test files + 6 custom test files. 9 .clj standard library modules under src/jolt/clojure/ and src/jolt/jolt/. All builds/runs via jpm test. § Protocol system: Type registry in context env (:type-registry) maps type-tag→proto-name→method-name→fn. Three dispatch special forms: protocol-dispatch (resolves method via registry or reified methods), register-method (stores impl in registry), make-reified (creates anonymous object with :jolt/protocol-methods). fn* forms emitted by extend-type/extend-protocol MUST be @[...] (array) for eval-list dispatch. Protocols are maps with :jolt/type :jolt/protocol and :methods map.
