feat: add AUR PKGBUILD for wowee-git

Adds a wowee-git PKGBUILD suitable for submission to the Arch User
Repository. Tracks the main branch HEAD; pkgver is auto-generated from
the commit count + short hash so no manual bumping is needed on new
releases.

Key design decisions:
- Real binaries installed to /usr/lib/wowee/ to avoid PATH clutter
- /usr/bin/wowee wrapper sets WOW_DATA_PATH to the user's XDG data dir
  (~/.local/share/wowee/Data) so the asset path works without any
  user configuration
- /usr/bin/wowee-extract-assets helper runs asset_extract pointed at
  the same XDG data dir; users run this once against their WoW client
- Submodules (imgui, vk-bootstrap) fetched from local git mirrors
  during prepare() as required by AUR source array rules
- vulkan-headers listed as makedepend (required by imgui Vulkan backend
  and vk-bootstrap at compile time; not needed at runtime)

Note: stormlib is an AUR dependency (aur/stormlib). Users will need
an AUR helper (yay, paru) to install it, or install it manually first.
