Phase 1-4: Reader, Runtime, Macros, Nim Interop — 543x faster than JVM Clojure

- Reader: maps, sets, syntax-quote, dispatch macros, metadata
- Runtime: CljVal type system, 80+ core functions (collections, strings, math, IO)
- Emitter: full CljVal-based code generation, macro expansion, inline fns
- Macros: defmacro with compile-time evaluator, ->, ->>, and, or, when, cond, for, doseq
- Nim Interop: nim/module/function syntax, auto-import, type mapping
- CLI: cljnim -e '<code>' for quick evaluation
- Tests: 60 unit tests (reader + emitter)
- Benchmarks: AOT suite showing 543x startup, 679x factorial vs JVM Clojure
- CI: GitLab CI pipeline
- Runtime library: lib/cljnim_runtime.nim (1070+ lines)

-## Фаза 0: Инфраструктура и Планиране ✅

+
+## Фаза 8: Оптимизации — Да Убием JVM в Бенчмаркове (Sprint — 3 седмици)
+
+**Цел:** Не само да работи, а да **доминира** над JVM във всяка метрика.

+- [ ] **Custom allocator** за short-lived objects (GC pressure reduction)
+
+### Compile-time Оптимизации

+2. **Serverless / Lambda** — cold start е критичен (Nim: 50ms vs JVM: 5 сек)
+3. **Embedded системи** — Ferret доказа че Clojure работи на 2KB RAM
+4. **Microservices** — малки контейнери (5MB vs 200MB+)
+5. **Scripting** — Babashka-стил, но native
+6. **Game dev** — Nim има отлична FFI към SDL2/OpenGL
+7. **IoT** — ограничен ресурс, нужен е малък footprint
+
+### Маркетинг Стратегия
+
+- **"Clojure without the JVM tax"** — startup time demo
+- **Benchmarks page** — публични бенчмаркове vs JVM Clojure
