cellucid 0.9.0

[0.9.0] - 2026-01-01

This release graduates Cellucid Python out of alpha (still pre-1.0).

Added

• AnnData-first viewing and serving with .h5ad and .zarr support (lazy/backed loading where possible).
• Unified cellucid serve CLI with auto-detection for .h5ad, .zarr, and pre-exported dataset directories.
• Jupyter notebook integration (CellucidViewer, AnnDataViewer, show(), show_anndata()) with event hooks and session export.
• Session bundle support (.cellucid-session) including CellucidSessionBundle and apply_cellucid_session_to_anndata() for round-tripping highlights and user-defined fields back into AnnData.
• Multi-dimensional embedding exports (1D/2D/3D/4D) and vector-field overlays (RNA velocity / drift) via prepare() and vector_fields helpers.
• Hosted web UI proxy mode with on-disk caching helpers (get_web_cache_dir(), clear_web_cache()).

Changed

• Export format now includes explicit dataset identity metadata (dataset_identity.json) for reproducible sharing and session compatibility checks.
• Reduced export size and improved load performance with optimized manifests, improved connectivity edge export, and optional quantization + gzip compression knobs.

Security

• Session bundles are treated as untrusted input with bounds checks and dataset mismatch policies when applying to AnnData.

Documentation

• Major Read the Docs expansion and restructuring (Python package + web app guides), plus new publishing and contributing documentation.
