Codeman maintainer 28b44237ae fix(remote): classify the has-session probe by exit status, and forget it once the pane is back
#355 made the remote auto-reconnect watcher revive a dead pane only when the
durable remote tmux session is verifiably still alive, which is the right rule:
a clean Ctrl-C / Ctrl-D / exit tears that session down and must never relaunch
a fresh agent. Its probe, though, read `has-session`'s stdout and treated an
empty string as "gone". `tmux has-session` prints NOTHING on success (measured
on a scratch socket: exit 0, empty stdout, the failure message goes to stderr),
so every live remote session classified as gone and transport-drop reconnects
were silently disabled along with the clean-exit revives.

The probe now goes by exit status through a pure, unit-tested mapping
(`classifyRemoteAliveExit`): 0 is alive; ssh's own 255, a timeout (`killed`,
no numeric code) and a spawn failure are unknown, which the watcher already
treats as do-not-revive; any other status is the remote command's and means
gone (tmux's 1 for a missing session, 127 when tmux is not installed there).

Two smaller things in the same area:

- The cached answer was never invalidated, so after one successful reattach a
  stale `true` would have revived the NEXT clean exit (the original bug back
  after the first transport drop), and a cached `false` from a clean exit would
  have left a manually restarted session with auto-reconnect permanently off.
  The tick now forgets the cache entry whenever the pane is seen alive.
- The fire-and-forget probe has a 15s timeout against a 5s tick, so an
  unreachable host stacked up to three ssh processes per dead session. An
  in-flight set caps it at one.

The probe command is pinned as a literal string, and the reattach-then-clean-exit
sequence is driven through the watcher in the tests.
