### Added

- **Compact tool activity mode** (`simplified_tool_calling`, default on) — groups tool calls and thinking traces into a single collapsed "Activity" disclosure card per assistant turn. Also adds a new **Calm Console** theme with earth/slate palette and serif prose. @Michaelyklam — #1282
- **PDF first-page preview** — `MEDIA:` `.pdf` files render a canvas thumbnail via PDF.js CDN (4 MB cap). **HTML sandbox iframe** — `.html`/`.htm` files render inline in a sandboxed `<iframe srcdoc>` (256 KB cap). 10 i18n keys × 7 locales. @bergeouss — #1280, closes #480 #482
- **Inline Excalidraw diagram preview** — `.excalidraw` files render as pure SVG (no external deps; rectangles, ellipses, diamonds, text, lines, arrows, freehand; 512 KB cap). @bergeouss — #1279, closes #479
- **Inline CSV table rendering** — fenced `csv` blocks and `MEDIA:` CSV files render as scrollable HTML tables with auto-separator detection. @bergeouss — #1277, closes #485
- **Inline SVG, audio, and video rendering** — SVG as `<img>`, audio as `<audio controls>`, video as `<video controls>`. @bergeouss — #1276, closes #481
- **Batch session select mode** — multi-select sessions for bulk Archive/Delete/Move. 11 i18n keys × 7 locales. @bergeouss — #1275, closes #568
- **Collapsible skill category headers** — click to collapse/expand without re-render; state persists across filter cycles. @bergeouss — #1281
- **`providers.only_configured` setting** — opt-in flag to restrict the model picker to explicitly configured providers. @KingBoyAndGirl — #1268
- **OpenCode Go model catalog** — adds Kimi K2.6, DeepSeek V4 Pro/Flash, MiMo V2.5/Pro, Qwen3.6/3.5 Plus. @nesquena-hermes — #1284, closes #1269

### Fixed

- **Profile `TERMINAL_CWD` TypeError** — `_build_agent_thread_env()` helper merges env before `_set_thread_env()` call. @hi-friday — #1266
- **Service worker subpath cache bypass** — regex now matches `/api/*` under any mount prefix. @Michaelyklam — #1278
- **SSE client disconnect leaks** — `TimeoutError`/`OSError` treated as clean disconnects; server backlog 64, threads daemonized; session list renders before saved-session restore. @KayZz69 — #1267
- **i18n locale corrections** — Korean MCP strings (23), Chinese MCP strings (23), zh-Hant missing keys (41), de missing keys (229). @bergeouss — #1274, closes #1273

/**
* Hermes WebUI Service Worker
* Minimal PWA service worker — enables "Add to Home Screen".
* No offline caching of API responses (the UI requires a live backend).
* Caches only static shell assets so the app shell loads fast on repeat visits.
