Add custom nodes, Civitai loras (LFS), and vast.ai setup script

Includes 30 custom nodes committed directly, 7 Civitai-exclusive
loras stored via Git LFS, and a setup script that installs all
dependencies and downloads HuggingFace-hosted models on vast.ai.

+# Wildcard System - Project Summary
+
+## Overview
+
+Progressive on-demand wildcard loading system for ComfyUI Impact Pack with dynamic prompt support, UTF-8 encoding, and comprehensive testing.
+
+**Status**: ✅ Production Ready
+**Test Coverage**: 86 tests, 100% pass rate
+**Documentation**: Complete PRD, design docs, and testing guide
+
+---
+
+## Core Features
+
+- **Wildcard Expansion**: `__wildcard__` syntax with transitive multi-level expansion
+- **Dynamic Prompts**:
+  - Basic selection: `{option1|option2|option3}`
+  - Weighted selection: `{10::common|1::rare}` (weight comes first)
+  - Multi-select: `{2$$, $$red|blue|green}` with custom separators
+- **UTF-8 Support**: Korean, Chinese, Arabic, emoji, special characters
+- **Pattern Matching**: Depth-agnostic `__*/name__` syntax
+- **On-Demand Loading**: Progressive lazy loading with configurable cache limits
+- **Error Handling**: Circular reference detection, graceful fallbacks
+
+---
+
+## Architecture
+
+### Implementation
+- `modules/impact/wildcards.py` - Core LazyWildcardLoader and expansion engine
+- `modules/impact/impact_server.py` - Server API endpoint (/impact/wildcards)
+- `modules/impact/config.py` - Configuration with quoted path support
+
+### Key Design Decisions
+- **Lazy Loading**: Memory-efficient progressive loading strategy
+- **Transitive Expansion**: Multi-level wildcard references through directory hierarchy
+- **Case-Insensitive Matching**: Fuzzy matching for user convenience
+- **Circular Reference Detection**: Max 100 iterations with clear error messages
+
+---
+
+## Testing
+
+### Test Suites (86 tests)
+1. **UTF-8 Encoding** (15 tests) - Multi-language support validation
+2. **Error Handling** (10 tests) - Graceful error recovery
+3. **Edge Cases** (20 tests) - Boundary conditions and special scenarios
+4. **Deep Nesting** (17 tests) - 7-level transitive expansion + pattern matching
+5. **On-Demand Loading** (8 tests) - Progressive loading with cache limits
+6. **Config Quotes** (5 tests) - Configuration path handling
+7. **Dynamic Prompts** (11 tests) - Statistical validation of dynamic features
+
+### Test Infrastructure
+- Dedicated ports per suite (8188-8198)
+- Automated server lifecycle management
+- Comprehensive logging in `/tmp/`
+- 100% pass rate with statistical validation
+
+---
+
+## Documentation
+
+- **[README](README.md)** - Quick start and feature overview
+- **[PRD](WILDCARD_SYSTEM_PRD.md)** - Complete product requirements
+- **[Design](WILDCARD_SYSTEM_DESIGN.md)** - Technical architecture
+- **[Testing Guide](WILDCARD_TESTING_GUIDE.md)** - Test procedures and validation

+
+## Quick Start
+
+### Basic Usage
+```python
+# Simple wildcard
+"a photo of __animal__"
+
+# Dynamic prompt
+"a {red|blue|green} __vehicle__"
+
+# Weighted selection (weight comes FIRST)
+"{10::common|1::rare} scene"
+
+# Multi-select
+"{2$$, $$happy|sad|angry|excited} person"
+```
+
+### Running Tests
+```bash
+cd tests/
+bash test_encoding.sh
+bash test_error_handling.sh
+bash test_edge_cases.sh
+bash test_deep_nesting.sh
+bash test_ondemand_loading.sh
+bash test_config_quotes.sh
+bash test_dynamic_prompts_full.sh
+```
+
+---
+
+## Key Implementations
+
+### Weighted Selection Syntax
+**Correct**: `{weight::option}` - Weight comes FIRST
+- `{10::common|1::rare}` → 91% common, 9% rare ✅
+- `{5::red|3::green|2::blue}` → 50%, 30%, 20% ✅
+
+**Incorrect**: `{option::weight}` - Treated as equal weights
+- `{common::10|rare::1}` → 50% each ❌
+
+### Empty Line Filtering
+Filter empty lines AND comment lines:
+```python
+[x for x in lines if x.strip() and not x.strip().startswith('#')]
+```
+
+### Config Path Quotes
+Strip quotes from configuration paths:
+```python
+custom_wildcards_path = default_conf.get('custom_wildcards', '').strip('\'"')
+```
+
+---
+
+## Limitations
+
+- Weighted selection supports integers and simple decimals only
+- Complex decimal weights may conflict with multiselect pattern detection
+- Circular references limited to 100 iterations
+- Prefer integer weight ratios for clarity
+
+---
+
+## Performance
+
+- **Lazy Loading**: Only load wildcards when needed
+- **On-Demand Mode**: Progressive loading based on cache limits
+- **Memory Efficient**: Configurable cache size (0.5MB - 100MB)
+- **Fast Lookup**: Optimized directory traversal with pattern matching
