Security: lock down the TutorBot tool sandbox (shell exec is opt-in, all filesystem/shell access confined to the bot workspace) and isolate per-user resources, closing #518, #517, #516, #515, #514 and #506 (first hardened in #507). Bug fixes: chat input disabled after the first turn (#520), KB embedding failure on long documents (#521 / #509), profile creation under Docker (#512 / #513), Qwen reasoning models failing native tool calling (#527 / #528), the GPT-5 init-wizard token parameter (#508), and oversized session-event truncation (#524). Features: HTTP/SSE API for multi-turn chat with a specific TutorBot (#511), multimodal image fallback for vision-capable providers without a capability entry, safe ZIP knowledge upload, and a /settings/network page with model fetching (community PRs #522 and #523 reimplemented locally). Also bumps __version__ to 1.4.1, adds the v1.4.1 release notes, updates the README Releases section, and ships the Astro + Starlight docs site under site/.
