Enabling oxfmt default features in tasks/website_formatter is a potentially significant packaging/CI regression (extra deps, slower builds, possible platform constraints) and doesn’t clearly follow from making the Rust CLI formatting-only. Also, relying on cfg_attr(... expect(irrefutable_let_patterns)) in FormatRunner weakens compile-time guarantees; a small cfg-split can encode the invariant more robustly.

Summary of changes

Summary

This PR narrows the pure Rust oxfmt CLI to be a formatting-only entrypoint and gates non-formatting modes behind the napi feature.

Key changes

• Mode::{Init,Lsp} are now #[cfg(feature = "napi")]
  • apps/oxfmt/src/cli/command.rs wraps the --init and --lsp flag parsing in cfg(feature = "napi") blocks.
  • When napi is not enabled, only the formatting output mode parser is exposed with a Mode::Cli(OutputMode::Write) fallback.
• FormatRunner assumes Mode::Cli
  • apps/oxfmt/src/cli/format.rs keeps the Mode::Cli destructure, adding a cfg_attr to silence the irrefutable pattern lint when napi is disabled.
• main.rs becomes formatting-only
  • Removes the match over Mode and always initializes tracing/miette/rayon then runs FormatRunner.
• Website formatter now uses oxfmt default features
  • tasks/website_formatter/Cargo.toml switches from default-features = false to default features enabled.
