chore: keep the dev launch config out of this PR, and silence a lint warning

`.claude/` is gitignored (while `launch.json` is tracked), so its local
desktop-dev tweak slipped in through `git add -u` — reverted here, it stays a
local change. Also puts a comment in `deferred()`'s placeholder so it stops
tripping noEmptyBlockStatements.
