 refactor(permission-controller)!: Add messenger alternative to restricted method hooks (#8551) 
## Explanation

Adds a `messenger` option to permission specification builders as an
alternative to `methodHooks`, aligning spec builders with the
messenger-based method middleware introduced in #8506. Restricted-method
specs can now declare the root-messenger actions they need via
`actionNames` and consume a minimally-scoped `Messenger`.

Incidentally, also removes the `factoryHooks` and `validatorHooks`
fields from the spec builder surface. Both of these were unused in
practice.

consumer packages to resolve them

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> Breaking type-surface changes to permission specification builders
(removing `factoryHooks`/`validatorHooks` and adding optional scoped
`messenger`) may require downstream updates; new messenger delegation
logic could impact how restricted-method specs invoke host actions.
> 
> **Overview**
> Restricted-method permission specification builders can now receive an
optional scoped `messenger` (constructed from spec-declared
`actionNames`) as an alternative to relying on `methodHooks`, enabling
specs to call only explicitly-delegated host actions.
> 
> Introduces `createRestrictedMethodMessenger` (exported from the
package) to create a child `Messenger` with a minimal delegated action
surface, and adds tests covering delegation behavior and the new builder
option. **BREAKING:** removes `factoryHooks`, `validatorHooks`, and
related export fields from the permission specification builder API
surface.
