feat: migrate to @metamask/messenger-cli for action types codegen

[cryptodev-2s]

Explanation

Migrates from the deprecated messenger-generate-action-types binary in @metamask/messenger to the new standalone @metamask/messenger-cli package.

Changes

• Add @metamask/messenger-cli@^0.1.0 as devDependency to snaps-controllers
• Add per-package scripts following topic:action pattern:
  • messenger-action-types:check — checks if generated files are up to date
  • messenger-action-types:generate — generates/updates action type files
• Add root scripts delegating to snaps-controllers
• Integrate --check into lint and --generate into lint:fix
• Remove old generate-method-action-types script

References

• Depends on feat: extract generate-action-types CLI into @metamask/messenger-cli core#8378

Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've highlighted breaking changes using the "BREAKING" keyword

Note

Low Risk
Low risk: changes are limited to developer tooling (scripts, lint integration, and devDependencies) and should not affect runtime behavior, though CI/lint may fail if the new action-type generation checks differ from the old ones.

Overview
Migrates action-type code generation in snaps-controllers from the deprecated messenger-generate-action-types binary to the standalone @metamask/messenger-cli (messenger-action-types).

Updates root and package scripts to use messenger-action-types:check during lint and messenger-action-types:generate during lint:fix, removes the old generate-method-action-types script, and adds @metamask/messenger-cli as a devDependency (with associated yarn.lock updates).
