Issue URL: https://rommark.dev/claude/ide/session/session-1769083280612-mdof554ot

## Progress

### Iteration 1 - Add Close Buttons to Project Tabs - COMPLETED

**Discovery:**
- Session tabs (Level 2) already had close buttons implemented in session-tabs.js line 100
- Project tabs (Level 1) were missing close buttons entirely

**Changes Made:**

1. **project-manager.js** - Added close button to project tabs:
   - Modified `renderProjectTab()` to include close button element (line 192)
   - Added `closeProject()` method with confirmation dialog
   - Added `getSessionName()` helper method for displaying session names in confirmation
   - Close button removes project tab but keeps sessions accessible
   - Auto-switches to next available project when active project is closed

2. **project-tabs.css** - Added styling for project tab close buttons:
   - Added `.project-tab .tab-close` styles (lines 101-122)
   - Close button hidden by default, shows on hover
   - Red highlight on hover with rotation effect
   - Added mobile responsive styles to always show close button on small screens

**Implementation Details:**
- Close button uses × (multiplication sign) character
- Click event stops propagation to prevent triggering project switch
- Confirmation dialog shows session count and list for non-empty projects
- Graceful handling when last project is closed (shows empty state)

## Next Steps
- Test the implementation in browser
- Verify close buttons work on both project and session tabs
- Ensure responsive behavior on mobile devices
