Fix a misleading workspace comment and drop four dead config keys

visible_windows' doc comment claimed windows show "on the active
workspace of whichever monitor they're assigned to" - the code never
reads w.monitor at all; current_workspace is one flat value shared by
every monitor, not per-output. Documented that explicitly on both the
field and the method, since this is a real behavioral difference from
Hyprland worth a reader actually seeing, not just an inaccurate comment
to fix quietly.

monitor.primary_workspace/monitor.workspace_count describe a per-
monitor-workspace design that doesn't exist; workspace.auto_switch/
workspace.persistent were never wired to any behavior. All four were
seeded into default_config() and documented in DEFAULTS.md, so
srd.set()/srd.get() on them silently succeeded while doing nothing --
removed from both, matching the precedent already set by general.
rounded_corners' deliberate absence from default_config for a
different reason (backend-dependent default rather than unbuilt).
