Harden Jupyter lifecycle and enhance E2E browser UX tests

app.sh: full Jupyter env isolation (CONFIG_DIR, DATA_DIR, RUNTIME_DIR,
IPYTHONDIR), auto port allocation, foreground mode, restart command,
graceful stop (SIGTERM → wait → SIGKILL), orphan detection, stale
runtime JSON cleanup, reset-state command.

test_browser_ux.py: add TestNavigationClickThrough (click Plan A link,
verify target opens; click forward-link in Plan D), TestWidgetInteraction
(run all cells, verify output areas, click quiz Submit and verify feedback),
TestProgressPersistence (kernel API session, progress file schema validation).

.gitignore: add Jupyter isolation directories.
