Update README and architecture docs to emphasize:
- Complete independence from Java ecosystem (JVM, GraalVM, Closure)
- Native HAMT persistent data structures built from scratch in Nim
- Multi-target compilation (native, shared lib, WASM, JS)
- AI-native tooling and concurrency without JVM threads
Updates both English and Bulgarian documentation.
- New docs/index.md with language selector
- docs/en/ — 01-getting-started, 02-architecture, 03-ai-integration,
04-api-reference, 05-user-guide, 06-roadmap
- docs/bg/ — same structure in Bulgarian
- Root README.md trimmed to quick-start + links to docs/
- Removed old flat docs/ files (ARCHITECTURE.md, AI_FIRST.md, etc.)
- Added swap!/reset! examples to getting-started guides
