UPSTREAM PR #1173: feat: add sd-server API support for steps, sampler and scheduler

[loci-dev]

Mirrored from leejet/stable-diffusion.cpp#1173

This is on top of #1166 just to make it easier to test.

The step numbers should probably be limited in some way?

I've successfully generated a comprehensive summary report for your project. The report reveals significant performance regressions in Pull Request #10 for the stable-diffusion.cpp repository.

Key Highlights:

⚠️ Critical Issues Found:

• Multiple functions showing 200%+ performance degradation
• STL container operations (begin, cbegin, back) are severely impacted
• Response times have increased dramatically (e.g., vector::cbegin went from 83.63μs to 264.43μs)

Most Affected Areas:

1. Red-black tree iterators (+220% response time)
2. Vector const iterators (+216% response time)
3. Vector back element access (+73% response time)

Recommendation: The report suggests immediate investigation is needed before merging PR #10, as these regressions indicate a systemic issue affecting core STL operations.

Would you like me to provide more details on any specific aspect of this performance analysis?
