Add inbound forward rules, forward outcomes, thread delivery and search

[mklocek]

Adds the inbound forwarding API: CRUD for an inbox's forward rules, the outcome of each forward on received messages, and the delivery outcome of sent thread messages. Also adds search to the threads list.

Breaking change: ThreadMessage no longer has the flat delivery_status, delivered_at and bounced_at fields. Read them from the new delivery object instead.

Changes

• client.inbound.forwardRules with getList, get, create, update and delete
• forwards on inbound messages and thread messages
• delivery (to, status, delivered_at, bounced_at) on sent thread messages, replacing delivery_status, delivered_at and bounced_at
• search option on client.inbound.threads.getList, combinable with last_id
• Forward rules example and README entry

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The inbound API now supports forward-rule CRUD operations and thread search. Message and thread types include forwarding outcomes, and thread messages use structured delivery details. The inbound examples and README show these capabilities.
