Subject: [PATCH] feat(makefile): add patch target for automated version
 management (#8719)

* feat: Add version management to Makefile for streamlined updates

* Introduced a new `patch` target in the Makefile to update version numbers across all projects.
* The target updates `pyproject.toml` and `package.json` files, syncing backend and frontend dependencies.
* Includes error handling for missing version argument and cleanup of backup files after updates.

* refactor: Replace sed commands with Python scripts for version updates in Makefile

* Updated the `patch` target in the Makefile to use Python for modifying version numbers in `pyproject.toml` and `package.json`, enhancing readability and maintainability.
* Removed cleanup of backup files as they are no longer created with the new approach.

* chore: Update Makefile to remove frozen flag from uv sync command

* Modified the `patch` target in the Makefile to remove the `--frozen` flag from the `uv sync` command, allowing for more flexible dependency synchronization.
* This change enhances the update process for backend dependencies.

* chore: Enhance Makefile patch target with validation and parallel dependency syncing

* Updated the `patch` target in the Makefile to include validation checks for version changes in `pyproject.toml` and `package.json`.
* Implemented parallel execution for syncing backend and frontend dependencies to improve efficiency.
* Added final state validation to ensure expected files are modified after the update process.
* Improved user feedback during the version update process with clear success and error messages.
