feat: replace all e2e/UI tests with autotest, add revealInProjectExplorer

- Delete test/e2e/ (Playwright) and test/ui/ (vscode-extension-tester)
- Remove @playwright/test and vscode-extension-tester deps
- Remove test-ui script, update test-e2e to use autotest
- Add revealInProjectExplorer test to project-explorer plan
- Add Write Job Summary step to CI workflows
- Add LLM env vars to CI for failure analysis

Coverage: 48 steps across 2 plans covering 8 scenarios:
  - Project Explorer: focus, link, unlink, revealInProjectExplorer
  - File Operations: create class, create package, rename, delete

Scenarios NOT migrated (require native OS file dialogs):
  - addLibraries, addLibraryFolders, java.project.create

Local verification: 48/48 passed (31/31 + 17/17)
