fix: move generate_fixtures to standalone crate + bump to 1.0.0-beta.8

The beta.7 fix (required-features) prevented the binary from compiling
but Tauri's bundler reads Cargo metadata and still tried to copy every
declared [[bin]] into the bundle — failing on all 4 platforms with:
  'Failed to copy binary ...generate_fixtures: does not exist'

Fix: move generate_fixtures entirely out of the src-tauri package into
tools/generate-fixtures/ (its own Cargo.toml, only depends on image).
Tauri's bundler never scans outside src-tauri/, so the binary is fully
invisible to the release build.

To regenerate test fixtures:
  cargo run --manifest-path tools/generate-fixtures/Cargo.toml

+### Fixed
+- Release build failures on all platforms: the beta.7 fix used Cargo `required-features` to exclude `generate_fixtures` from compilation, but Tauri's bundler still reads `Cargo.toml` metadata and tries to copy every declared `[[bin]]` into the bundle — failing because the binary was never compiled. Fix: moved `generate_fixtures` to a completely independent Cargo crate at `tools/generate-fixtures/` that `tauri build` never sees. To run: `cargo run --manifest-path tools/generate-fixtures/Cargo.toml`.
