Summary

Replace deprecated asyncio.get_event_loop().run_until_complete(coro) with asyncio.run(coro) in CLI entry points (browser-use skill-cli main entry).

Problem

Issue #4626 / #4447: browser-use fails on Python 3.14 because asyncio.get_event_loop() raises RuntimeError when called outside an async context (behavior was removed/changed in Python 3.14).

Fix

In browser_use/skill_cli/main.py, replace all 5 occurrences of:

• loop = asyncio.get_event_loop(); loop.run_until_complete(...) with asyncio.run(...)
• asyncio.get_event_loop().run_until_complete(...) with asyncio.run(...)

asyncio.run() is the recommended approach since Python 3.7 and works correctly on Python 3.14. Compatible with Python 3.11+ (repo requires Python >=3.11,<4.0).

Changes

• browser_use/skill_cli/main.py: 5 occurrences fixed (setup, doctor, tunnel stop --all, tunnel stop , tunnel start)
• tests/ci/test_cli_entry_points.py: NEW - 169 lines of tests covering setup, doctor, tunnel entry points + regression tests verifying get_event_loop() is NOT called

Testing

• All tests pass on Python 3.11+
• Added regression tests to ensure asyncio.get_event_loop() is never called during CLI execution

Fixes #4626
Fixes #4447

Summary by cubic

Fix CLI crashes on Python 3.14 by replacing deprecated event loop calls with asyncio.run. Adds tests to prevent regressions across setup, doctor, and tunnel commands.

• Bug Fixes
  • Replaced all asyncio.get_event_loop().run_until_complete(...) with asyncio.run(...) in browser_use/skill_cli/main.py for setup, doctor, and tunnel (start/stop/--all).
  • Added tests/ci/test_cli_entry_points.py covering CLI entry points and asserting asyncio.get_event_loop() is never called.
