Fix project switching bug where case-insensitive matching worked but
caused database lookup failures for subsequent operations.
**Problem:**
- switch_project('personal') succeeded (case-insensitive matching)
- get_current_project() failed with 'Project personal not found'
- Session stored user input case instead of canonical database name
**Solution:**
- Find project by permalink (case-insensitive) in switch_project
- Store canonical project name from database in session
- Use canonical name for all API calls and responses
**Test Coverage:**
- Added comprehensive case-insensitive project switching tests
- Added tests for case preservation in project listings
- Added tests for session state consistency after case switching
- Added error handling tests for non-existent projects
**Files Changed:**
- src/basic_memory/mcp/tools/project_management.py: Fixed switch_project logic
- test-int/mcp/test_project_management_integration.py: Added test coverage
**Test Cases Now Passing:**
- ✅ switch_project('personal') → finds 'Personal' project
- ✅ get_current_project() → works with canonical name
- ✅ Project summary shows stats correctly
- ✅ Case-insensitive matching for all case variations
- ✅ Error handling for non-existent projects
