Add escape menu and weapon slot tooltips to character sheet

- Escape Menu:
  - Opens with Escape key from base game screen
  - Resume button to return to game
  - Exit Game button to quit application
  - Character sheet closes with Escape if open (takes priority)
  - Mouse capture/release handled by UI components

- Weapon Slot System:
  - Visual weapon boxes (80x80) in character sheet
  - Display weapon icons from WeaponData
  - Empty slots appear dimmed
  - Hover tooltips show weapon stats (not clipped by containers)
  - Tooltips display: slot name, weapon name, damage, range, cooldown, knockback, block percentage
  - Tooltips positioned globally to avoid ScrollContainer clipping

- Bug Fixes:
  - Fixed typo in lilguy_body.gd (dwextends -> extends)
  - Removed manual mouse toggle from player (now handled by UI)

- Updated character_sheet.gd to use weapon slot components instead of text labels
- Added weapon_tooltip.tscn as separate scene for unclipped tooltips
