v0.2.2

### Features

- **MAIC Editor (v0) — slide editing surface** — A new **Pro Mode** toggle turns any generated slide into an editable canvas: select and edit text, insert text boxes and images, navigate and reorder slides from a thumbnail rail, with history-aware undo/redo. This is the first surface of the broader MAIC Editor framework (gated behind `NEXT_PUBLIC_MAIC_EDITOR_ENABLED`) [#615](https://github.com/THU-MAIC/OpenMAIC/pull/615)
- **Editable outline before generation** — The streaming course outline now morphs into an inline editor: review, edit, reorder, and add or delete scenes and bullet points, then confirm to generate the full course — so you catch structure problems before spending a full generation [#558](https://github.com/THU-MAIC/OpenMAIC/pull/558)
- **Offline-ready classroom export** — Exported teaching resource packs and classroom ZIPs now inline external assets so interactive pages open fully offline, even when copied to another machine [#613](https://github.com/THU-MAIC/OpenMAIC/pull/613)

### Bug Fixes

- **Server-configured providers are now admin-managed** — providers set via server environment can no longer be overridden by client settings, preventing base-URL/key tampering on shared deployments [#624](https://github.com/THU-MAIC/OpenMAIC/pull/624); fixes server API-key fallback when the client echoes the provider base URL [#533](https://github.com/THU-MAIC/OpenMAIC/pull/533) (by @LooThao); auto-selects the server LLM model [#577](https://github.com/THU-MAIC/OpenMAIC/pull/577) (by @xuruiray); and enforces a "usable provider ⇒ concrete model" invariant [#581](https://github.com/THU-MAIC/OpenMAIC/pull/581)
- Keep interactive scenes alive across remounts with an iframe keep-alive pool, so interactive content no longer reloads when navigating [#629](https://github.com/THU-MAIC/OpenMAIC/pull/629)

- Skip shapes with malformed SVG paths instead of aborting the whole PPTX export [#505](https://github.com/THU-MAIC/OpenMAIC/pull/505); prevent memory leaks and silent export failures [#552](https://github.com/THU-MAIC/OpenMAIC/pull/552) (by @arnow117)
