Sylpheed RE agent 0efd692b4c docs: the suite is heavy, not hung -- correcting my own "cannot terminate"
Last iteration I wrote that build-reborn test cannot finish in a working
session, from having watched it run 3h26m. That was the stronger claim
and I made it without measuring the work.

Timing `mesh info` on each of the 166 .xpr containers with a 25 s cap:

  files scanned                166
  exceeding 25 s                19   Hangar, 17 Stage_*, ptc_pack
  Stage_S02 to completion      144 s, rc = 0

Nothing hangs. Nineteen heavy containers at roughly two minutes each is
about 45-60 minutes for one pass, before the 147 fast ones. The 3h26m
observed was that hour of work running at a load average of 9-14 --
inflated by the two duplicate runs I had left going, which did not merely
coexist with the slowness but multiplied it.

The practical conclusion is unchanged and only the wording softens: an
hour-scale suite is not an iteration-scale gate, and every "green" I
reported from it this session was partial. But an hour-scale gate can be
run deliberately, whereas a hung one cannot be run at all, so the
distinction is worth having right.

File list committed as reference data so the cost is attributable without
re-scanning.

METHOD: a slow thing observed under contention looks like a stuck thing;
measure the work before choosing between "cannot finish" and "takes an
hour".
