Reverts 45b6c347, which kept nothing of such a message and raised an aged-out
condition: that departed from an accepted decision on a lead's word alone. The
concern behind it (the record keeps the subject, with no age) is its own issue.
A record kept without its body still carried its subject, which names whose mail it was, with no age. The lead decided such a message is not kept at all: the notice is taken, the message counted, and the log and an aged-out condition say how many messages of the stream aged out undelivered. Unrestricted streams are unchanged.
DEAD_LETTERS kept a message given up on MAIL forever and showed it whole to any caller of dead-letters, outside the grant and past MAIL's week. Per ADR 0376 §3-§6: the kept copy carries a per-message time to live of what is left of its stream's age (a copy already past it is kept without its body), DEAD_LETTERS and EVENTS allow per-message TTL, the list and show give no body or own headers for it, delivering it again needs a minute left and the copy keeps the time left, and its max-deliveries condition clears saying how many aged out undelivered and from which stream.

A seat's queue made again numbers from one, so an old dead letter's sequence
can name a live ask; deleting by number alone would drop it silently. An ask
with no worker would wait unseen while counted as delivered.

A build ask its seat's worker gave up on could only be dropped, though the
controller already holds the publish on that seat's accepts and the stream
API to remove the original. Asks to other seats stay refused: delivering them
needs a grant ADR 0264 withholds, in the asker's name ADR 0259 protects.

The give-up time is not newer for every letter kept: a notice that could
not be kept is offered again a minute later, so a later give-up can be kept
first and the one after it read as not fresh. The stored time rises with the
stream's sequence. A consumer whose letters vanish between the two reads is
left out of the look instead of counted as a look, and the skip of a
token-less max-deliveries advisory now has a test of its own.

The dead-letter row and a max-deliveries advisory without a token both said
bus.<stream>.<consumer>.max-deliveries: each look added an observation and a
line of evidence through the row, and the two overwrote each other's words.
The row owns the key since issue 330, so the advisory watcher leaves it, and
the row now says when the newest held message was given up, so a letter held
for a day no longer reads as observed every 30 seconds. Times without Happened
is refused, since the raise ignored it and an update counted it.

A dead letter was let go as delivered even when its consumer did not filter
its again subject; seat asks needed a grant over every seat's queue and left
the original stuck; a notices bind failure stopped the controller (review).
Design 25 promised a dead-letter stream that did not exist: a message a
consumer gave up on stayed only in its source, which drops it after a week,
and its condition cleared when the advisories stopped (hq issue 330, ADR 0264).
