Added #

• HTTP foundation using Dio: base URL handling (appends /api), timeouts, and idempotent retries (429/5xx/network) with jitter via retry.
• Request/response logging (debug-only).
• Unified error handling: map Misskey error responses to MisskeyApiException(statusCode/code/message).
• Auth token auto-injection: inject i into POST JSON bodies when authRequired is true; per-request options via RequestOptions(authRequired/idempotent).
• Minimal common model and client for /api/meta (Meta + MetaClient), including a tiny cache and supports(keyPath) capability detection.
• JSON serialization setup (json_serializable/json_annotation) and generated code.
• Example app (example/): sign-in using misskey_auth, note posting, timeline, following/followers tabs; Riverpod for state; loader_overlay for loading UI.
• OAuth helper site under pages/ (index.html, redirect.html) and GitHub Pages deploy workflow (.github/workflows/deploy-pages.yml).
• Android/ iOS URL-scheme setup for OAuth callback; Android INTERNET permission.
• Unit tests: token injection, error mapping, retry behavior, and Meta serialization/capability; example smoke test.
