🔧 chore: update eslint v2 configuration and suppressions (#12133)

* v2 init

* chore: update eslint suppressions and package dependencies

- Removed several eslint suppressions related to array sorting and reversing from eslint-suppressions.json to clean up the configuration.
- Updated @lobehub/lint package version from 2.0.0-beta.6 to 2.0.0-beta.7 in package.json for improvements and bug fixes.
- Made minor formatting adjustments in vitest.config.mts and various SKILL.md files for better readability and consistency.

* fix: clean up import statements and formatting

- Removed unnecessary whitespace in replaceComponentImports.ts for improved readability.
- Standardized import statements in contextEngineering.ts and createAgentExecutors.ts by adding missing spaces for consistency.

* chore: update eslint suppressions and clean up code formatting

* 🐛 fix: use vi.hoisted for mock variable initialization

Fix TDZ error in persona service test by using vi.hoisted() to ensure
mock variables are available when vi.mock factory runs.

This works for small arrays, but can be slower or just throw an error for very large arrays due to spread operator limitations.
