feat(oxlint): defer more oxlint config to categories

[mcous]

In the same spirit as my ESLint config, this PR takes a pass at reducing my oxlint config to defer to builtin categories as much as possible

This results in a handful of new rules turning on, so this PR also fixes violations in this repo

Changes

Linting Configuration and Code Quality Updates

Layer / File(s)	Summary
Root oxlint rules refactoring packages/oxc-config/src/lint.ts	The main oxlint configuration replaces a large prior ruleset with a smaller curated set grouped by correctness, perf, suspicious, pedantic, restriction, and nursery categories. Plugin configuration is adjusted, and test file overrides are updated to relax TypeScript unsafe/non-null assertion rules while refining Vitest checks.
Package and tooling configuration updates packages/oxc-config/package.json, packages/create/oxlint.config.ts, tsconfig.json	Package version bumps to 0.2.0, a new create package oxlint config extends the root and disables typescript/no-unsafe-type-assertion, and TypeScript compiler adds allowImportingTsExtensions to support .ts extension imports.
Create package utility improvements packages/create/src/fetch-package-versions.ts, packages/create/src/read-manifest.ts, packages/create/src/copy-configs.ts, packages/create/src/create-manifest.ts	Four utilities are improved for clarity and correctness: explicit null check replaces falsy check in version resolution, manifest reader initializes contents as empty string with clearer typing, config copier uses descriptive variable naming, and manifest creator simplifies callback form.
