feat: Merge GPT-5 enhancements with working c72a240 base + restore crawler

Major update combining the stable c72a240 Hugging Face deployment base
with GPT-5 improvements from 057c21e.

## Core Enhancements Added:

### GPT-5 Model Support (Step 1 of 15)
- Three-tier model system: nano/mini/main for different use cases
- model_router (gpt-5-nano): Fast routing and classification
- model_translator (gpt-5-mini): Translations and summaries
- model_analyzer (gpt-5): Complex analysis and comparisons
- Verbosity control: low/medium/high response lengths
- Reasoning effort: minimal/medium/high thinking depth
- Task-specific presets for optimal parameters

### Files Modified:
- analyzer/llm_client.py: Added GPT-5 support with model types
- analyzer/config.py: Added GPT-5 model configurations
- src/analyzer/*: Synced all files to match analyzer/ base

### Crawler Restored:
- analyzer/crawler/snapshot.py: Grant page scraping
- analyzer/crawler/discover_grants.py: Grant URL discovery
- Both restored from 057c21e commit

### Preserved from c72a240 Working Base:
- ✓ 7 preset questions (including past winners)
- ✓ Async batch processing
- ✓ All optimizations (caching, context reduction)
- ✓ Clean UI (no emojis)
- ✓ Reliable regex-based query routing
- ✓ 36 grants loading correctly

### Tests Passed:
- All imports successful
- 36 grants loaded
- GPT-5 models configured correctly
- Crawler modules working
- LLM client ready

Both analyzer/ and src/analyzer/ directories are now identical
and contain the working c72a240 base + GPT-5 enhancements.
