Extracted from #318 (the UTF-8/doctor core, minus the env-wrapper feature):
- new agent_reach/utils/process.py: utf8_subprocess_env() +
mcporter_utf8_env_args() — Windows GBK consoles otherwise corrupt
Chinese output from mcporter/MCP child processes
- weibo/douyin/linkedin checks and weibo install/registration now pass
the UTF-8 env (and register the MCP server with --env PYTHONUTF8=1)
- youtube: extract _has_js_runtime_config() with an OSError guard so an
unreadable yt-dlp config can't crash doctor
- test_skill_command: open SKILL.md with explicit utf-8 (Windows GBK
default broke these tests)

- YouTube: warn when only Node.js is installed but yt-dlp config file
is missing (previously returned "ok" incorrectly)
- Douyin: use `mcporter list` instead of calling with a hardcoded
invalid share URL that always fails
- cli: replace bare `except:` with `except Exception:` in
`_detect_environment` to avoid catching KeyboardInterrupt/SystemExit
- cli: fix unclosed file handle for cloud VM detection
- config: use `os.open()` with 0o600 mode to eliminate permission
race window when saving credentials
- Replace text=True with encoding='utf-8', errors='replace' in all
subprocess.run calls (channels + cli.py) to fix GBK decode errors
on Chinese Windows systems
- Use shutil.which() resolved paths in channel subprocess calls to
handle Windows .cmd wrappers (npm global installs)

mcporter list probes all configured servers sequentially, which can hang
indefinitely when servers are slow/offline. mcporter config list reads
config without probing — sufficient for checking if a server is configured.
Affected: doctor checks (4 channels) and install command (2 calls).
Fixes#34
