This pull request introduces several new utility functions to the src/common directory, improves test organization, and refactors the cache hook to use a safer and more robust parameter stringification strategy. It also updates documentation and dependency management to reflect these changes.

New utility functions and testing improvements:

• Added new utilities: hasOwnProperty, toArray, early, and isPlainObject in src/common, each with in-source Vitest tests for improved maintainability and coverage. [1] [2] [3] [4]
• Moved the clone utility's tests into in-source Vitest blocks and removed the separate test file, streamlining test code and reducing file clutter. [1] [2]

Cache hook improvements:

• Replaced the custom stableStringify function with the new stringifyParams utility (which uses safe-stable-stringify) for serializing cache keys, making cache key generation crash-safe and more robust to edge cases like circular references and non-JSON values. Updated documentation and type hints accordingly. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]

Internal codebase refactoring:

• Updated all hooks that previously imported toArray from internal.utils to now import it from the new common location, reflecting its promotion to a public utility. [1] [2] [3] [4]

Documentation and dependency updates:

• Added a new CLAUDE.md file detailing the project's structure, conventions, and commands, providing clear guidance for contributors.
• Added the safe-stable-stringify dependency and updated pnpm-lock.yaml accordingly. [1] [2] [3] [4]

These changes improve utility discoverability, make the codebase more robust and maintainable, and enhance documentation for current and future contributors.
