PR #69 review round 2.
- The herdr probe is tri-state (present / absent / unknown) from a parsed
`_herdr agent list`: absent only when the list parses without the name or
herdr answers server_not_running. A failed, unparseable or timed-out lookup
is unknown and keeps the marker (codex P1: has-session's exit 1 meant both
"absent" and "lookup failed").
- Probes run with MAM_NO_AUTOSTART=1 so a check never starts a server (agy P2).
- Probe time is capped by max(deadline, start + PROBE_FLOOR_S=2 s), shared by
all markers, so a slow herdr cannot hold the wait or its lock past the cap
(codex P2); MAM_ID_ORDER_WAIT_S=0 still gets one bounded look.
- Tests: unknown probe keeps and refuses; delayed probe at caps 0/1/3 stays
within the bound; real probe via lib.sh mam_id_order_wait against mock herdr
(listed / unlisted / failing list / server_not_running).

A create/resume killed after spawning its pane but before registering its
row left a marker whose owner pid was dead; the next same-cwd waiter pruned
it on the pid alone and could start a second session that discovers the
same workspace conversation id (PR #69 review P1).
- Markers record the herdr server. A dead owner's marker is pruned only once
its row is registered for the attempt (running, newer epoch: the row
decides) or `_herdr has-session` reports the session gone; an unanswered
probe counts as alive. On timeout the kill-session command is printed.
- A live marker of another process for the waiter's own session name is kept
and blocks instead of being deleted; the waiter's own pid's markers go.
- Tests: orphan / registered / gone / same-session / missing pane pid cases,
and a create-level reproduction against mock herdr (fails before the fix).
