feat: hourglass (#1543)

# v1.8.0 Hourglass

The Hourglass release consists of a framework that supports the creation
of task-based AVSs. The task-based AVSs are enabled through a
`TaskMailbox` core contract deployed to all chains that support a
`CertificateVerifier`. Additionally AVSs deploy their
`TaskAVSRegistrar`. The release has 3 components:

1. Core Contracts
2. AVS Contracts
3. Offchain Infrastructure

The below release notes cover Core Contracts. For more information on
the end to end protocol, see our
[docs](https://github.com/Layr-Labs/hourglass-monorepo/blob/master/README.md)
and [core contract docs](../docs/avs/task/TaskMailbox.md).

## Release Manager

@0xrajath 

## Highlights

This hourglass release only introduces new contracts. As a result, there
are no breaking changes or deprecations.

🚀 New Features

Destination Chain Contracts
- `TaskMailbox`: A core infrastructure contract that enables task-based
AVS execution models. It provides a standardized way for AVSs to create
tasks, have operators execute them, and submit verified results
on-chain. The contract acts as a mailbox system where task creators post
tasks with fees, and operators compete to execute and submit results
with proper consensus verification.
