l0ng-ai 16370ed30a docs(cli): record what the capture settle timer actually costs ...

`tty7 capture` takes ~323ms against a local daemon and neither constant said
why. Measured: a pane that has printed nothing costs the same as one holding
22,000 lines, `--plain` costs the same as raw, and lowering the replay grid's
floor from 10,000 lines to 100 changes nothing. The grid work is ~20ms; the
rest is `REPLAY_SETTLE` running out. `tty7 pane ls` over the same socket is
~5ms.

It is paid because the replay has no end. The daemon sends `Size` then
`Snapshot` per ring segment and stops, and the only way to know it has stopped
is to wait. Live `Output` cuts the wait short, so a busy pane returns at once
— but the idiom the reference recommends is `tty7 wait … && tty7 capture …`,
and `wait` returns exactly when the pane has gone quiet. The recommended path
always pays in full.

No behaviour change; this is the note that was missing. It also records the
two wrong ways out, because both look attractive from the outside. Lowering
the timer trades a bounded delay for silently truncated output on a slow link
or a loaded machine. An end-of-replay message is the real fix and is *not*
additive — `DaemonMsg::read` rejects an unknown kind outright, so a daemon
sending one to an older client breaks it. That needs a `PROTOCOL_VERSION` bump
with the daemon gating on what the peer announced, which is a larger change
than a comment.
