- backends is now an ordered candidate list (first = preferred); channels
report the backend actually serving via active_backend, surfaced in the
doctor text report and --json
- new agent_reach/probe.py really executes upstream commands and tells
apart missing / broken (stale venv shebang after a system Python
upgrade) / timeout, with a reinstall prescription for broken installs
- all 13 channels migrated off which()-only checks: fixes bilibili
false-positive "bili-cli 可用" on broken shims, misleading xiaohongshu
"连接失败", rdt OSError crashing doctor, mcporter breakage masquerading
as "未配置"
- twitter: 15s probe + 1 retry (flaky 10s timeout), broken twitter-cli
now falls back to bird instead of aborting the check
- doctor survives per-channel exceptions; config supports per-channel
backend override (<channel>_backend / <CHANNEL>_BACKEND env)
- fix skill install/uninstall crash on symlinked skill dirs (the
"[Errno None] None" warning from shutil.rmtree on a symlink)

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)

- 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
