Slash command:
- Fix first-click bug: set textarea.value and cursor position before
calling handleInputChange so selectionStart reads correctly
- Move slash button to right of + (attach) button
- Simplify icon from CommandLineIcon to plain "/" text
Composer action bar:
- Move Agent toggle and permission selector to left side (was centered)
- Adjust spacing: reduce input padding, increase bottom margin
Permission selector:
- Add dropdown arrow indicator (ArrowDown01Icon)
- Change full_access color from orange to red (icon + text + background)
- Check res.ok before updating UI state (prevent false success)
- Make sessionId optional to support /chat new session page
- Log warnings on PATCH failure instead of silent catch
New chat page (/chat):
- Add ChatPermissionSelector with local state before session exists
- Pass permission_profile in session creation payload
- Backend createSession() now accepts and writes permission_profile
Context usage indicator:
- Reduce circle size from 22px to 16px
- Change used-portion color to dark gray (zinc-600/400)
