Wire aspect_ratio, phone_mode and pin_input through config/IPC/CLI

The Lua and IPC/CLI surface for the three new core primitives
(crates/core: aspect_ratio rule action, general.phone_mode, virtual-
pointer window pinning):

- srd.rule(..., { aspect_ratio = "9:16" }): parses a "W:H" string into a
  validated (u32, u32), rejecting a malformed value as a real Lua error
  at config-load time rather than silently ignoring it.
- general.phone_mode config default, plus srd set phone_mode <bool> for
  the live equivalent (same shape as animations/shadows/rounded_corners).
- pin_input IPC dispatch ({"cmd":"pin_input","pid":<pid>,"id":<window
  id>}, id omitted to unpin) and its CLI surface, srd dispatch pin input
  <pid> <window-id> / unpin input <pid>. Keyed by the owning client's
  process id, not an opaque per-object id nothing outside the Wayland
  backend could ever learn - a controlling tool already knows its own
  pid for free.

See docs/TODO.md for the full design reasoning behind each of these.
