Single oxc CLI Binary

[vosatom]

Currently, oxc tools are distributed as separate binaries (oxlint, oxfmt, etc.). It might make sense to have a single oxc binary that wraps all tools under one CLI using subcommands — similar to how Biome approaches this with biome lint, biome format, and biome check.

The idea is to have a single oxc binary with lint and fmt or other subcommands that mirror the existing CLIs, so oxlint --fix src/ would become oxc lint --fix src/. This would be purely optional - the existing oxlint and oxfmt binaries would remain as-is, so you could still install only what you need.

One of potential benefits is binary size. Would this be something worth considering?
