Phase 14 fixes: pr-str mapping, every-pred, PLAN.md update

- compiler.janet: fix core-pr-str mapping — was pointing to core-str (line 221)
- core.janet: add core-pr-str (string/format-based serialization with proper quoting),
  add core-every-pred (variadic predicate composition), wire both into core-bindings
- cljs-port-5.janet: restore var-dynamic? test, with-meta preserves test,
  add pr-str keyword and every-pred assertions
- PLAN.md: update to current state — all phases 0-14 checked off, 316/317

316 ok, 1 fail (pre-existing, unchanged)

+# Jolt — Complete Implementation Plan
+
+## Architecture Goal
+
+Minimal Janet bootstrap → SCI/CLJS Clojure source runs on Jolt.
+
+Three layers:
+1. **Janet runtime**: types.janet, reader.janet, evaluator.janet, compiler.janet (~4,200 lines)
+2. **Clojure core**: core.janet (~1,400 lines), phm.janet (~200 lines)
+3. **Clojure source** (.clj files loadable at runtime): stdlib modules, SCI
+
+## Current State
+
+| Metric | Value |
+|--------|-------|
+| Total tests | 317 |
+| Passing | 316 |
+| Failing | 1 (lang.cljc deftype — deferred to Phase 15) |
+| CLJS test files ported | ~15/60 |
+| Total assertions | 860+ across 24 test files |
+| Source lines | ~5,600 (7 core .janet files) |
+
+## Phase Plan
+
+### Phase 0-10: Foundation ✓
+
+| Phase | Description | Status |
+|-------|-------------|--------|
+| 0 | `defn` bug fix, bare symbol resolution | ✓ |
+| 1 | Var/Namespace system, ns form extensions | ✓ |
+| 2 | PersistentHashMap implementation | ✓ |
+| 3 | Var system: var-get/set/?, alter-var-root, intern, binding | ✓ |
+| 4 | deftype/defrecord completion | ✓ |
+| 5 | Multimethods + Hierarchy | ✓ |
+| 6 | Reader extensions: tagged literals, :jolt/tagged handler | ✓ |
+| 7 | LazySeq + PersistentHashSet | ✓ |
+| 8 | Protocol system: defprotocol, extend-type, extend-protocol, reify, satisfies? | ✓ |
+| 9 | REPL fixes: buffer-based output, collection rendering, cond fix | ✓ |
+| 10 | Standard Library: clojure.string, clojure.set, clojure.walk, clojure.zip, clojure.edn, clojure.java_io, jolt.interop, jolt.shell, jolt.http | ✓ |
+
+### Phase 11: Fix Pre-existing Failures ✓
+
+- `types.janet`: `ns?` now accepts both structs and tables
+- `core.janet`: `comment` macro wired into core-bindings
+- `sci/lang_stubs.clj`: minimal SCI type stubs for bootstrap
+- `test-load-sci.janet`: load stubs before SCI source files
+- **Result: SciVar fixed. 1 remaining (deftype with `#?@` — Phase 15)**
+
+### Phase 12: Core Feature Completion ✓
+
+- `apply` support in evaluator + compiler
+- `str` handles nil correctly
+- 6 CLJS test files created (~120 assertions)
+- `#()` anonymous fn reader with `%`, `%1`, `%2` arg handling
+
+### Phase 13: Protocol Completion ✓
+
+- reify dispatch: protocol methods work on reified objects
+- `#()` reader macro with gensym-based `%` arg handling
+- IFn protocol support in default invocation arm
+- clojure.walk loads and `keywordize-keys` works
+- 4 test sections: reify dispatch, anon fn, extend-type, walk loading
+
+### Phase 14: Extend CLJS Ported Tests ✓
+
+- `cljs-port-2.janet` expanded: 10 sections (12-21), 35→60 assertions
+- `cljs-port-5.janet` created: sections 22-24, destructuring, metadata, fn composition
+- `pr-str` compiler fix: maps to new `core-pr-str` (not `core-str`)
+- `every-pred` added to core.janet
+- `var-dynamic?` and `with-meta` tests restored
+
+### Phase 15: SCI Bootstrap
+
+- Complete `sci.lang` namespace with Var type
+- Load remaining SCI namespaces
+- SCI test runner
+- Fix SciVar `#?@` deftype issue
+
+### Phase 16: Remaining Core Library + Tests
+
+- Port ~20 remaining CLJS test files
+- Fix found gaps: `&` rest destructuring, `seq` nil handling, vector/list equality
+- `eval`, `syntax-quote` completion
+
+### Phase 17: Optimization
+
+- Compiler improvements: inline small core functions
+- PersistentHashMap dynamic bucket growth
+- Benchmarks
+
+### Phase 18: Standard Library Completion
+
+- Complete EDN reader/writer
+- Complete java.io wrappers
+- clojure.zip tests
+
+## Implementation Order
+
+1. ✅ Phases 0-14 (completed)
+2. Phase 15 (SCI bootstrap) — **critical path**
+3. Phase 16 (remaining test porting + feature gaps)
+4. Phases 17-18 (optimization, stdlib)
