feat: Enhance dependency extraction to capture pip installs and binary downloads

This commit adds three major improvements to dependency tracking:

1. pip/uv install command extraction:
   - Captures package==version patterns from pip/uv install commands
   - Adds 4 new vLLM dependencies: torch, torchaudio, torchvision, lmcache

2. GitHub release URL extraction:
   - Extracts versions from wget/curl GitHub release download URLs
   - Handles multiline RUN commands in Dockerfiles
   - Adds 1 new sglang dependency: nats-server v2.10.28

3. TensorRT-LLM install script coverage:
   - Added install_nixl.sh to trtllm component configuration
   - Adds 1 new trtllm dependency: UCX v1.18.1

Impact:
- Total dependencies: 243 → 249 (+6 new)
- Closes gap where hardcoded versions in scripts were missed
- Improves accuracy of dependency tracking across all components
