Use oxc for linting/formatting

[IzumiSy]

Replace ESLint and Prettier with oxlint and oxfmt from the oxc project.

Why

• Performance: oxlint/oxfmt are written in Rust and finish in ~30ms across the entire codebase. Benchmarks suggest oxlint is faster than Biome as well. I am satisified with the speed enough.
• Simpler config: No plugin dependency chains — each package has a small self-contained .oxlintrc.jsonc
• Fewer dependencies: Removes a large number of ESLint-related packages (~2,000 lines removed from lockfile)

Added configuration for oxfmt as well, but I would like to separate the PR to apply the all file formatting due to the number of files that need formatting. Let me open the another PR later just for formatting files.
