docs(live-verify): fold in #637/#639/#642 and correct the #630 entry's close() → destroy()

[vibechoom]

Noticed while checking citations for the rest of this sweep. Class: routine post-burst coverage lag on the manual-verification checklist, plus one entry that now names the wrong GTK call.

Coverage

docs/live-verify.md:17 declares "Coverage: #458 through #634". Merged since f7a980d (#636, the last refresh): ee96105 (#637), 743e106 (#639), cacd997 (#642).

#637 and #639 each carry a substantive "## Live-verify note". #637's asks for a glib::WeakRef / gtk::Window::toplevels() count check across repeated kanshi hot-plug cycles for never-opened layer windows — a real un-CI-testable gesture that currently exists nowhere but a merged PR body, which is exactly the loss this file was created to prevent (#611's own note: "this file goes stale within minutes of a merge burst, so updating it belongs to the burst rather than to a later pass").

The #630 entry names a call the code no longer makes

docs/live-verify.md:359-361 tells the verifier the fix means close_all "no longer holds the PANELS RefCell borrow across each window.close() call". trollshell/src/modal.rs:1008 now reads panel.window.destroy();, changed by #637, whose comment at modal.rs:1000-1003 explains why close() was wrong. The entry is phrased in the present tense as what the current code does, so a reader diffing it against modal.rs sees a mismatch.

What I checked and dropped

I expected #642 (the corrected default station id) to need a caveat, since crates/hytte-services/src/places.rs:341 writes the default config only when places.toml is absent — which would make the departures steps at docs/live-verify.md:160/:193 read as a false pass against an existing config. That is already handled outside this file: the #641 triage comment says so verbatim ("Your existing file won't be fixed by that … You'll need to edit ~/.config/trollshell/places.toml yourself") and #640 is open on the missing editor UI. No doc change is needed for it beyond the coverage line.

Severity: low. Three PRs of lag on a file the maintainer folds in by habit, plus a one-word correction. It is worth writing down only because #637's toplevel-count gesture is recorded nowhere else.

Recommendation

Fold #637/#639/#642 in and bump the coverage line at :17 to #642, carrying #637's toplevels()-count gesture across verbatim. While there, change close() to destroy() at docs/live-verify.md:359-361. Good rider on the next docs PR; not worth a standalone one.
