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).
