feat: support dev buys via rehype

[Zodomo]

Description

Using transient storage we can open a temporary window for the first buy atomically bundled with an Airlock.create call to be exempted from non-protocol fees assessed by the rehype hook. By redesigning Bundler such that it calls into Uniswap's PoolManager directly, we can further constrain access to this window within the hook to the bundler only, such that ERC-4337 AA userOp bundling cannot inadvertently trigger the exemption. In this way, dev buys can be enabled only for the first swap atomically combined via our bundler explicitly. Any integrators or wrappers will have to call into our bundler, rather than delegating control to their own contracts. Only one exact-input buy using the configured numeraire is allowed, multi-hop routing is not supported. All of this preparation takes place within pool initialization, and because transient storage is used, these preparations are dropped if no buy transaction is bundled on launch. Dev buys can optionally be vested with an optional cliff and configurable durations as well.

Motivation

Many teams and integrators have asked for the ability to perform "dev buys", which is understood to be a fee exemption on the first post-market creation swap for teams launching new assets. Many teams configure their launches with an aggressive anti-sniper decaying fee, often starting at 80%, so this can make it difficult for them to acquire tokens from the market first. This mechanism allows them the exclusive privilege to buy without non-protocol fees assessed, without having to worry about timing their entry along the decaying tax curve. The tokens purchased can also be vested to increase community confidence.

Changes

• Redesigned Bundler to atomically create a market and execute one exact-input buy directly through Uniswap v4’s PoolManager.
• Added a transient, pool-specific Rehype fee exemption restricted to the authorized Bundler; the Airlock owner fee remains assessed.
• Added optional linear vesting with configurable cliff, duration, and permissionless or recipient-only claims.
• Added bundle simulation for quoting the resulting asset, pool, governance, timelock, and purchase output without retaining state.
• Updated deployment scripts and versioning to deploy Bundler before Rehype and bind the authorized Bundler address.
• Added integration, vesting, rollback, fee-exemption, simulation, and unsupported-initializer tests.
• Expanded CI coverage across primary contracts, initializers, Bundler, Rehype, migrators, and invariants.
• Updated Rehype documentation and added Bundler documentation.
