docs: close #93 and #80 (indoor lighting) — user re-verified 2nd-floor fix

"Number 80 is closed, I verified again." Moved #93 (the lighting
umbrella) and #80 (2nd-floor darkness) to Recently closed. #94
(held-item spotlight) is NOT folded into this closure and stays open —
user confirmed acdream doesn't support equipping hand-held items yet,
so it's currently untestable; marked BLOCKED rather than an active A7
target so it doesn't keep resurfacing as unfinished lighting work.
