chore: bootstrap Anvil repo skeleton

First commit on feature/v0.1.0 establishes the Hellion Forge plugin
scaffold:

- .gitattributes: Linux-first LF defaults, Windows-script CRLF exceptions,
  binary markers for fonts / images / archives. Pre-empts the
  Forgeimizer pre-push hook crash that was caused by Asriels CRLF default.
- .editorconfig: Hellion Forge .NET conventions
  (private fields _camelCase, Allman braces, var-preferred).
- .gitignore: VisualStudio baseline + secrets bucket + Anvil.Tests
  excluded (build-suite lives in the local Hellion Build test repo).
- LICENSE: MIT, Hellion Online Media 2026.
- NOTICE.md: goodwill attribution to Craftimizer and clean-room
  anonymisation note.
- PRIVACY.md: zero-telemetry statement matching 00-Anvil-Scope.
- README.md: v0.1.0 status + planned-feature outline + custom-repo URL.
- Anvil.sln + Anvil/Anvil.csproj: Dalamud.NET.Sdk/15.0.0, x64 platform
  pinned (forge-wide rule), Microsoft.Extensions.Hosting stack closed-range
  pin to 10.0.7 matching HellionChat v1.5.0. No DalamudPackager.targets
  override - SDK 15 default packager handles images / icon / image_urls.
- Anvil/Anvil.yaml: plugin manifest with explicit icon_url / image_urls
  (top-level fields required for SDK 15 default packager) and a v0.1.0
  changelog entry that names RecipeData as the first module.
