Add Burglin' Gnomes BepInEx ultrawide UI plugin

Config-driven so values are tunable without recompiling or pasting console
scripts. Camera is deliberately untouched - it is orthographic with constant
orthographicSize, which is already correct Hor+ at 32:9.

Fixes the two UI families separately, each via the lever that actually works:
- HUD (ScreenSpaceOverlay/ScaleWithScreenSize): match=1 + referenceResolution.y
  raised by HudScale, shrinking the HUD while giving the layout more room.
- World labels (WorldSpace): canvas transform localScale, because
  CanvasScaler.scaleFactor is overwritten by HandleWorldCanvas every frame.

Baselines are cached per canvas so periodic re-apply never compounds.
