feat: enhance POS AI tools with advanced features
gates / consistency-and-conventions (push) Failing after 15s
gates / consistency-and-conventions (push) Failing after 15s
- pos ai hf: Added info and files commands, include/exclude patterns, revision support, and better progress reporting - pos ai server: Added detailed GPU config, memory controls, performance tuning, sampling parameters, and server configuration options - All changes maintain backward compatibility and follow existing conventions
