Implement general.focus_follows_mouse/auto_raise; remove the rest as dead

Auditing "clicking behavior and basics": general.focus_follows_mouse,
general.mouse_follows_focus, general.auto_raise, general.auto_focus,
the entire window.* namespace (8 more keys, a full duplicate of the
same four plus remember_position/size/state), and general.
smart_placement/border_width were all seeded into default_config() and
documented in DEFAULTS.md, but none were read anywhere - srd.set()/
srd.get() on any of them silently succeeded while doing nothing.

focus_follows_mouse is real, well-defined, and directly relevant to
clicking basics - implemented it plus auto_raise (raise, not just
focus, on hover) rather than just deleting the promise like the
others. WindowManager gained focus_follows_mouse/auto_raise bools,
wired from apply_general_settings the same way every other general.*
flag is. handle_pointer_position now tracks whichever window (content
or decoration) is under the pointer and, when the setting is on and
that differs from the currently-focused window, focuses it through the
same focus_window() free function every click-driven focus change
already uses (real keyboard focus, not just core state) - skipped
entirely while dragging/resizing or over a layer-shell surface, so the
pointer sweeping over other windows mid-drag or hovering a bar can't
steal focus from what's actually being manipulated.

mouse_follows_focus (pointer warp on keybinding-driven focus change)
and auto_focus (no clear distinct meaning beyond click-to-focus) stay
unimplemented and are now undocumented rather than promised.
