feat(create): add OXC toolchain (oxlint + oxfmt)

Adds OXC as a third toolchain option alongside ESLint and Biome for
both React and Solid frameworks. OXC is a Rust-powered toolchain from
the oxc-project that is 10-100x faster than ESLint and 30x faster than
Prettier.

- oxlint: fast linter (stable v1.x)
- oxfmt: Prettier-compatible formatter (beta v0.x, 100% JS/TS conformance)

Each framework gets:
- info.json with exclusive linter slot, priority 3 (after ESLint=0, Biome=2)
- package.json with lint/format/check scripts
- .oxlintrc.json config (React variant includes react plugin)
- .oxfmtrc.json config
- small-logo.svg
