Replace highlight.js/lib/common (36 languages) with a curated subset
of 16 languages relevant for coding-assistant chat UIs. Both ToolCall
(direct hljs) and ChatMessage (rehype-highlight) now share the same
custom bundle from src/lib/highlight.ts.
Languages included: bash, css, diff, dockerfile, go, ini, javascript,
json, markdown, python, rust, shell, sql, typescript, xml, yaml.
Markdown chunk: 477KB → 336KB (-30%, -45KB gzipped)
Adds a 'System' option to the theme switcher that automatically uses
light or dark theme based on the OS prefers-color-scheme setting.
Dynamically updates when the OS preference changes (e.g. scheduled
dark mode). i18n labels added for EN/FR.
- Add split view button (columns icon) in sidebar session actions
- Click to open any session in a secondary pane alongside the primary
- Resizable divider between panes (drag to resize, persisted in localStorage)
- Secondary pane supports full chat: history, streaming, send, abort
- Close split view via X button or clicking the split icon again
- Each pane has independent scroll, search, and tool collapse
- Keyboard shortcut and i18n support (EN/FR)
Add a {} button (visible on hover) that toggles a collapsible panel
showing the full raw gateway JSON payload for any message.
Includes copy-to-clipboard, word-wrap, and i18n (EN/FR).
Useful for debugging and understanding the gateway protocol.
Closes feedback #52
Messages from /hooks/agent containing SECURITY NOTICE blocks and
<<<EXTERNAL_UNTRUSTED_CONTENT>>> delimiters are now cleaned up.
Only the actual user content is displayed, with a small webhook
badge indicator showing the message originated from a webhook.
Closes feedback #54
- Add ThemeContext with CSS custom properties for all base colors

- i18n support (EN/FR) for theme labels
When the agent is reasoning with hidden thinking (thinking=low), show a
pulsing 'Reasoning...' indicator with elapsed time instead of generic
bouncing dots. Once text content starts streaming, falls back to the
regular streaming dots.
Closes feedback #40
Small info button appears on hover of each message bubble.
Click to expand a panel showing raw message metadata (id, role,
timestamp, channel, sender info, etc.) from the gateway.
Useful for debugging and understanding message routing.
Collapsed by default, doesn't clutter the UI.
Closes feedback item #39

all tool call details at once. Useful for long conversations with many tool
calls where scrolling through expanded results is tedious.

- Sort sessions by most recently updated (within pinned/unpinned groups)
- Map updatedAt and lastMessagePreview from gateway sessions.list response
Replace raw session keys/UUIDs with readable names derived from
session metadata (label, kind, channel). Priority: label > kind-based
name (Main, Cron, Task) with channel suffix > cleaned key fallback.
New utility: src/lib/sessionName.ts used by both Header and Sidebar.
System events (heartbeats, cron triggers, webhooks, channel events)
now render as subtle inline notifications instead of full user bubbles.
Detection based on content patterns ([EVENT], [cron:], [HEARTBEAT], etc.).

Check typeof Notification before accessing .permission or
requestPermission(). Fixes crash on browsers/contexts where
the Notification API is unavailable (e.g. some WebViews).

and disable the connect button until it's valid. Prevents confusing
connection errors from malformed URLs.
Show a spinner with 'Loading messages…' text while chat history
is being fetched during session switches, instead of briefly
flashing the empty welcome screen. Includes EN/FR i18n.
Shows a subtle horizontal line with the date label (Today, Yesterday, or
full date) when messages span multiple days. Helps orient users when
scrolling through long conversation histories.
Includes i18n support (EN/FR) for the date labels.
Hover over any user message to reveal a retry button (↻) that resends
the message text. Disabled while a response is generating.
Includes EN/FR i18n strings.
