Fix project isolation: Make loadChatHistory respect active project sessions

- Modified loadChatHistory() to check for active project before fetching all sessions
- When active project exists, use project.sessions instead of fetching from API
- Added detailed console logging to debug session filtering
- This prevents ALL sessions from appearing in every project's sidebar

-# Task: Fix the missing 'x' close button on session/project tabs in the Claude IDE. The issue is at https://rommark.dev/claude/ide/session/session-1769083280612-mdof554ot - The two-level tab system (project tabs and session tabs) needs close buttons. Files to check: session-tabs.js, project-manager.js, project-tabs.css. Add close button functionality to both tab levels.
+# Task: CRITICAL BUG: Project isolation completely broken.
 
-<!-- COMPLETE -->
+## Current Behavior
+User creates new project (e.g., 'roman') and clicks 'Start new session' → ALL sessions from other projects appear in this project's left sidebar.
+
+## Previous Failed Attempts
+1. Virtual workingDir approach - didn't work
+2. Skipping virtual sessions in loadProjects() - didn't work
+3. Smart merging logic - still doesn't work
+
+## Requirements
+1. Each manually created project should have ONLY its own sessions
+2. Auto-generated projects (from real workingDirs) should still work
+3. Projects must persist across page refreshes
+4. Switching between projects should show only that project's sessions
+
+## Files to Analyze
+- /home/uroma/obsidian-web-interface/public/claude-ide/project-manager.js (main logic)
+- /home/uroma/obsidian-web-interface/public/claude-ide/chat-enhanced.js (left sidebar)
+- /home/uroma/obsidian-web-interface/routes/sessions-routes.js (backend API)
+
+## Success Criteria
+- Create new project 'test'
+- Add session to 'test' project
+- Only 'test' session appears in left sidebar (NOT all sessions)
+- Switching to another project shows only that project's sessions
+- Console logs confirm correct session filtering
+
+<!-- Ralph will continue iterating until task is complete -->
 
 ## Success Criteria
 
 The task is complete when:
-- ✅ All requirements are implemented (close buttons added to both tab levels)
-- ✅ Tests pass (code verified and committed)
-- ✅ Code is documented (inline comments and git commit message)
+- All requirements are implemented
+- Tests pass
+- Code is documented
 
-## Implementation Summary
-
-**Discovery:**
-- Session tabs (Level 2) already had close buttons implemented
-- Project tabs (Level 1) were missing close buttons
-
-**Changes Made:**
-
-1. **project-manager.js**:
-   - Added close button HTML element to `renderProjectTab()` method
-   - Implemented `closeProject()` method with confirmation dialog
-   - Added `getSessionName()` helper for displaying session names
-   - Auto-switches to next project when active project is closed
-   - Shows empty state when all projects are closed
-
-2. **project-tabs.css**:
-   - Added `.project-tab .tab-close` styling
-   - Close button hidden by default, appears on hover
-   - Red highlight on hover with rotation effect
-   - Mobile responsive: always visible on screens < 480px
-
-**Features:**
-- Click event stops propagation to prevent triggering tab switch
-- Confirmation dialog shows session count and list for non-empty projects
-- Graceful handling when closing the last project
-- Sessions remain accessible via API even after project tab is closed
