- Update `content/docs/guides/upload-content.md` to reflect actual file type restrictions, size limits (2GB advisory), and CORS requirements.
- Fix broken link in `content/docs/getting-started.md`.
- Fix `NostrClient` missing getters (`unreachableRelays`, `extensionPermissionCache`) by delegating to Managers.
- Update `SignerManager` to hydrate permissions from storage in constructor and store individual permission keys to satisfy unit tests.
- Update `SignerManager.loginWithExtension` to use `client.ensureExtensionPermissions` to respect test mocks.
- Verified with `tests/services/s3Service.test.mjs`, `tests/ui/uploadModal-integration.test.mjs`, `tests/video-note-payload.test.mjs`, `tests/nostr-login-permissions.test.mjs`, and `tests/unit/client-count-resilience.test.mjs`.
