Fix demo: install from PyPI + correct model id and framing

- requirements: install pgmap-align==1.5.2 from PyPI (was git+...@v1.2.0,
the source of the build error)
- app.py: SD1.5 model id runwayml/stable-diffusion-v1-5 (removed/401) ->
stable-diffusion-v1-5/stable-diffusion-v1-5
- de-claim NeurIPS acceptance / drop "anonymous"; BibTeX @inproceedings -> @misc ;
README PyPI line -> pip install pgmap-align

 Interactive demo for **PG-MAP** (Preference-Guided Adaptive MAP) — a training-free framework that re-optimizes the conditioning $c$ and the latent $z_t$ at every denoising step. Supports SD 1.5, SDXL, and SD3.5-medium (UG-FM) backbones.

 **Inference-time alignment for diffusion + flow-matching** — re-optimize the
 conditioning $c$ and the latent $z_t$ at every denoising step under a
 trajectory-level Gibbs-MAP / proximal energy objective. No training required.

 Pick a backbone, write a prompt, hit **Generate**. Toggle PG-MAP off to compare against the static baseline at the same seed. Default hyperparameters match the paper table; the sliders expose the productive ranges.
