v2.0.1

Code-review cleanups and a full dependency refresh.

Changes

• Remove unused dependencies (aegis, dirs, direct tower)
• Mirror the 401 force-refresh retry into the OpenAI chat_completions path
• Deserialize OpenAI requests from a borrow to avoid cloning the request body
• Consolidate useUsageHistory onto the generated OpenAPI client, dropping duplicate hand-written types and raw fetch calls
• Upgrade Rust dependencies (tower-http 0.7, plus compatible bumps)
• Upgrade frontend dependencies including majors: TypeScript 6, @types/node 26, @vue/tsconfig 0.9, @hey-api/openapi-ts 0.99; regenerate the API client
