Config at ~/.config/srd; cursor shapes, key repeat, pin, mouse defaults

Config path drops a level: ~/.config/srd, not ~/.config/srdwm/srd, which
said the same thing twice. No other user-facing path had the same problem --
srdwm reads the config dir and writes nothing else.

Cursor shapes. A client's own cursor surface is now rendered with the
hotspot it declared, so an I-beam over text or a hand over a link shows the
app's image instead of srdwm's arrow. The built-in arrow stays as the
fallback when no client has set one, over decorations and the desktop.
Named shapes still fall back to the arrow; most toolkits set a surface.
Decorations and cursors now share one OverlayElement type, since
render_output takes a single custom-element slice.

Key repeat (srd.bind_repeat, Hyprland's binde). Held volume, brightness and
switcher keys repeat at the seat's own rate rather than firing once. Driven
from the poll loop, not a timer source: the winit backend has no calloop
loop of its own, and poll_events already runs continuously in both backends.
Repeat stops when *that* key is released, not when any key is.

Always-on-top / pin, for the picture-in-picture and HUD rules that used it.
Window::always_on_top was another declared-but-never-read field. Enforced in
WindowManager's stacking order rather than at render time, so every consumer
of stacking_order gets it and none can forget to honour it.

Mouse-only window management, checked end to end: drag the titlebar to move,
drag any edge or corner to resize, titlebar buttons to close/maximise/
minimise, click to focus, drag to a screen edge to snap, and now
double-click the titlebar to maximise. The resize grab band went from 6px to
10px - a hairline is genuinely hard to hit with a mouse, which is why
Hyprland ships extend_border_grab_area.

Also removed the emoji status markers from docs/IMPLEMENTATION_STATUS.md.
