Upgrade examples and utilities to Agent SDK 2.0.0 and replace context-level sending with Conversation.sendText, Conversation.sendActions, and MessageContext.sendRemoteAttachment across the repository

Updates all examples and inline actions utilities to the SDK 2.x APIs, removing custom codecs, pinning @xmtp/agent-sdk to 2.0.0, and refactoring message, action, reaction, attachment, group, and transaction flows to use Conversation and SDK helpers. Adds CHANGELOG entries and bumps the root version to 0.0.9.

📍Where to Start

Start with the inline actions middleware and helpers in inline-actions.ts, then review example message handlers such as index.ts and attachment handling in index.ts.
