handoff: relaunch the tiers detached, progress numbers, new-episode copy run

The x265/nvenc tiers launched as Hermes background processes were killed
mid-encode at 10:37 when the user's session was closed, so persist_on_release
is not enough here: run/relaunch_tiers.sh starts them orphaned from Hermes
(Start-Process) with a retry loop, which is why they are no longer tracked and
must be stopped by PID only.

STATE.md now carries the progress table (242/589 done, 347 pending: 169 x265 +
174 nvenc + 4 copy), the reason a full `--tier copy` pass must NOT be run (its
only skip test is "already HEVC", which a copy output never satisfies - it
would redo all 193), and the four new weekly episodes handled one file at a
time.
