v0.1.11 — Multi-monitor handling: disable an auxiliary monitor before Gaming Mode

Browse Source 
Reported on a Framework Desktop (AMD AI MAX 380) + Gigabyte M27Q +
LG DualUp setup: with both monitors attached, gamescope would either
land on the wrong screen or refuse to start, and writing
OUTPUT_CONNECTOR=DP-X alone wasn't enough to fix it. The workaround
shipped by the user was to manually patch /usr/share/gamescope-session-plus
to disable the other monitor before launching gamescope.

DeckShift now handles this natively, without touching the
gamescope-session-plus script (which is ChimeraOS's, not ours):

- New env var OUTPUT_CONNECTOR_TO_DISABLE (single connector or
  comma list) written to ~/.config/environment.d/gamescope-session-plus.conf
  alongside the other display keys.

- switch-to-gaming reads it and runs `hyprctl keyword monitor X,disable`
  for each listed connector BEFORE the SDDM restart, while Hyprland is
  still alive (hyprctl needs a live IPC socket). The disable is
  runtime-only — Hyprland's static config isn't touched — so when the
  user returns from Gaming Mode the new Hyprland reads its config fresh
  and the monitor comes back automatically. No re-enable step needed.

- Settings TUI exposes this as a "Hide monitor" main-menu item. The
  picker lists every connected monitor EXCEPT the gaming one (so a
  user can't accidentally pick the same connector they just set as
  OUTPUT_CONNECTOR) and includes a "(clear)" entry.

Also fixes a latent bug in v0.1.10's config-path shortening:
${CONF/#$HOME/~} was supposed to render the conf path with ~ but
bash applies tilde-expansion to the replacement side, re-expanding ~
to $HOME and making the substitution a no-op. Escaped as \~ now.

## What's New
### v0.1.11 — Multi-monitor handling: disable an auxiliary monitor before Gaming Mode
- New env var `OUTPUT_CONNECTOR_TO_DISABLE` (single connector or comma list). When set, `switch-to-gaming` runs `hyprctl keyword monitor <conn>,disable` for each listed connector *before* SDDM restart, while Hyprland is still alive. The disable is runtime-only — when the user returns from Gaming Mode, the new Hyprland reads its static config fresh and the monitor comes back automatically.
- Settings TUI exposes this as a **"Hide monitor"** option in the main menu and on the state panel. The picker lists every connected monitor *except* the gaming one, plus a "(clear)" entry to remove the override.
- Fixes a reported issue on multi-monitor setups (e.g. Framework Desktop + LG DualUp + Gigabyte M27Q) where gamescope would either land on the wrong screen or refuse to start when both monitors were attached. The previous workaround was to physically unplug the second monitor.
- Also fixes a latent bug from v0.1.10: the config-file path in the TUI was supposed to render with `~` instead of `/home/<user>` to fit the panel, but bash's tilde-expansion on the replacement side of `${var/#pat/~}` re-expanded `~` back to `$HOME`, making the substitution a no-op. The replacement is now escaped as `\~`.
### v0.1.10 — Settings TUI layout polish
- Banner, state panel, menu header, and menu items now share a single centred panel column rather than each block centring itself independently. The TUI feels visibly aligned in a Walker floating window of any width — no more drifting elements off to the left while the menu floats to the right.
