* Clean up temporary JavaScript files and reorganize test files
- Remove temp_js_*.js files that appear to be development iterations
- Move test_simple_cost.js to tests/ui_tests/ where it belongs with other UI tests
- Move package.json to tests/ directory since it's only used for test dependencies (Puppeteer)
- These changes clean up the root directory from temporary development files
* chore: Clean up root directory and organize dev scripts
- Remove redundant app.py (was calling non-existent local_deep_research.main())
- Move development utility scripts to scripts/dev/:
- kill_servers.py: Flask server process management
- run_tests.py: Test runner with coverage
- debug_pytest.py: CI test debugging
- Fix kill_servers.py to use correct server command (local_deep_research.web.app)
* fix: Update UI tests workflow to use tests/package.json
The npm install command was looking for package.json in the root directory,
but it was moved to tests/ directory. Update the workflow to install npm
dependencies from the correct location.
* fix: Update full tests workflow to use tests/package.json
Another npm install command in the full tests workflow was looking for
package.json in the root directory. Update it to install from tests/
directory where the package.json is located.
