Fix Vader test runner: Install Vader.vim in Dockerfile and improve test execution
## Changes Made ### Dockerfile - Added Vader.vim installation during Docker build - Ensures Vader test framework is available in test containers ### scripts/user/run-vader-tests.sh - Improved error handling for Vader.vim installation - Changed to use Vim's -es mode (ex mode, silent) as recommended by Vader - Enhanced success detection to parse Vader's Success/Total output format - Added better error reporting with test failure details - Improved timeout handling and output capture ## Current Test Status ### Passing Tests (6/8 suites) - ✅ folding.vader - ✅ lint.vader - ✅ motion.vader - ✅ rope.vader - ✅ simple.vader - ✅ textobjects.vader ### Known Test Failures (2/8 suites) - ⚠️ autopep8.vader: 1/8 tests passing - Issue: pymode#lint#auto function not being found/loaded - Error: E117: Unknown function: pymode#lint#auto - Needs investigation: Autoload function loading in test environment - ⚠️ commands.vader: 6/7 tests passing - One test failing: PymodeLintAuto produced no changes - Related to autopep8 functionality ## Next Steps 1. Investigate why pymode#lint#auto function is not available in test environment 2. Check autoload function loading mechanism in Vader test setup 3. Verify python-mode plugin initialization in test containers These fixes ensure Vader.vim is properly installed and the test runner can execute tests. The remaining failures are related to specific python-mode functionality that needs further investigation.
