dx: xstreamroll-sdk README contains placeholder URLs and unimplemented features

[Xhristin3]

Problem Statement
xstreamroll-sdk/README.md references API endpoints and features (WebSocket subscriptions, paginateStreams()) that either do not exist in the current API or are not implemented in the SDK. New adopters following the README will encounter immediate failures.

Why It Matters
Documentation that doesn't match the implementation actively harms adoption.

Acceptance Criteria

• Full audit of xstreamroll-sdk/README.md against the actual SDK implementation
• Methods that don't exist marked clearly as (coming soon) or removed
• A working 'Quick Start' code example tested against the real API
• API compatibility table showing which SDK version works with which API version
• Auto-generate API reference from TSDoc comments using typedoc

Files Affected: xstreamroll-sdk/README.md, xstreamroll-sdk/src/

Difficulty: Easy | Effort: 1 day
