build: migrate workspace tooling to Oxc

Replace Turbo task orchestration with Bun workspace scripts and remove the Prettier configuration. Add Oxlint and Oxfmt project configuration, including Tailwind class sorting, generated-file exclusions, and unified check/fix commands. Apply the new formatter and resolve Hook dependency errors surfaced by Oxlint.
