- 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)

CRITICAL FIX: update.md was telling agents to uninstall bird CLI,
which broke users who had working bird installations. Now:
- twitter.py: prefers twitter-cli, falls back to bird/birdx if installed
- update.md: removed "clean up deprecated tools" step entirely
- Added explicit rule: "Never uninstall any existing tools the user already has"
- Tests cover twitter-cli primary + bird fallback + preference order
78 tests passing.

- Replace xreach CLI with bird (@steipete/bird) as Twitter/X backend
- bird uses AUTH_TOKEN/CT0 env vars (simpler than xreach's session.json)
- Accept both 'bird' and 'birdx' binary names
- Remove version detection logic (bird v0.8.0 is the baseline)
- Write credentials.env to ~/.config/bird/ for easy sourcing
- Keep xfetch session.json sync for backward compatibility
- Update SKILL.md commands: bird search/read/user-tweets/thread
- Update install/uninstall to use npm @steipete/bird
- All 52 tests pass
