docs(log): 041 — midiviz exits with the board, so 'always open' is conditional

Found while shutting down: unplugging the LCXL took midiviz's ALSA
source with it, the process exited cleanly, and Restart=on-failure did
not fire. The permanent lens is only permanent while the board stays
plugged -- which is the same resolve-once stale-binding shape as the
zombie driver this session was opened to fix. lcxl-leds.py already has
the fix pattern (re-resolve per send, cache invalidated on failure).

+- **midiviz does not survive a replug.** Observed at session end: PLN unplugged
+  the LCXL, `lcxl-path.py` went to "no LCXL on the bus", and `midiviz.service`
+  went **inactive** — it resolves its ALSA source port once at startup and exits
+  when the port disappears, and `Restart=on-failure` does not fire on a clean
+  exit. So the "always open" lens is only always-open while the board stays
+  plugged. `tools/lcxl-leds.py:557-641` already solves exactly this (re-resolve
+  on every send, 2s cache invalidated on failure) — midiviz should either adopt
+  that or the unit should use `Restart=always` with a short `RestartSec` so it
+  rebinds within seconds of a replug. This is the same stale-binding family as
+  the bug that started the whole session.
