refactor: UI cleanup - move respawn controls, remove mode label, fix dir width

- Move respawn controls from toolbar to session options modal
- Remove unnecessary Mode label from session options (visible in tab)
- Increase directory input width from 200px to 350px
- Add RTL direction to directory display to show end of long paths
- Add respawn status indicator with stop/configure buttons in modal

+
+## Frontend
+
+The web UI (`src/web/public/`) uses vanilla JavaScript with:
+- **xterm.js**: Terminal emulator with WebGL renderer for 60fps performance
+- **xterm-addon-fit**: Auto-resize terminal to container
+- **Server-Sent Events**: Real-time updates from `/api/events`
+- **No build step**: Static files served directly by Fastify
+
 ## Pending Tasks
 
+**Note to Claude: Do NOT remove or modify this section during /init. These tasks are actively being worked on by other sessions.**
+
 - [ ] Remove the "New Session" tab and add a gear icon (⚙️) in the top right corner for app settings
 - [ ] Add confirmation dialog when clicking "x" on a session tab - warn user that the screen session behind will be closed
 - [ ] In settings: add option to configure a default CLAUDE.md file path (e.g. /home/arkon/default/CLAUDE.md) that will be used for new sessions/cases
