User-visible changes only. Internal refactors and infrastructure work omitted.

## v1.0 — Launch

First generally-available release.

- Tenant-scoped persona configuration with system prompt, default params, avatar, and `draft` / `active` / `archived` lifecycle.
- Three RAG strategies (`single_step`, `multi_step`, `agentic`) with per-source weights and configurable top-k, min-score, and context template.
- ScaiMatrix collections and ScaiDrive shares as knowledge sources, both gated by per-call caller access checks.
- Publish / unpublish flow that materialises the persona as a tenant-namespaced frontend model with backend links and metadata inherited from the underlying model.
- Optional group assignment on publish, scoped to the caller's role.
- Avatar upload (PNG / JPEG / GIF / WebP / SVG; 2 MB max) with magic-byte validation and S3-backed serving.
- Standard / custom / none status-message modes for streaming RAG progress.
