feat: replace cloud translation with local Neural CLI

## Changes

### Removed (OpenAI-dependent)
- ❌ `.github/workflows/translation-sync.yml` - GPT-Translate workflow
- ❌ `docs/Development/translation-workflow.md` - OpenAI setup docs

### Added (Local Ollama-based)
- ✅ `Makefile`: New `make translate` target using Neural CLI
- ✅ `docs/Development/translation-guide.md` - Neural CLI guide

## Benefits

**Before (GPT-Translate)**:
- 💰 Monthly cost: ~¥90 (OpenAI API)
- 🔑 Requires API key setup
- 🌐 Data sent to external API
- ⏱️ Network latency

**After (Neural CLI)**:
- ✅ **$0 cost** - Fully local execution
- ✅ **No API keys** - Zero setup friction
- ✅ **Privacy** - No external data transfer
- ✅ **Fast** - ~1-2 min per README
- ✅ **Offline capable** - Works without internet

## Technical Details

**Neural CLI**:
- Built in Rust with Tauri
- Uses Ollama + qwen2.5:3b model
- Binary size: 4.0MB
- Auto-installs to ~/.local/bin/

**Usage**:
```bash
make translate  # Translates README.md → README-zh.md, README-ja.md
```

## Requirements

- Ollama installed: `curl -fsSL https://ollama.com/install.sh | sh`
- Model downloaded: `ollama pull qwen2.5:3b`
- Neural CLI built: `cd ~/github/neural/src-tauri && cargo build --bin neural-cli --release`
