fix: add encoding='utf-8' to all file operations to prevent UnicodeEn…

[programminx-askui]

This pull request standardizes file reading and writing operations across the codebase to always specify encoding="utf-8". Additionally, it updates the project's coding guidelines to reflect this requirement and introduces new Git best practices.

File encoding standardization:

• Updated all file read and write operations (e.g., Path.read_text(), Path.write_text()) in multiple modules to explicitly specify encoding="utf-8", ensuring proper handling of Unicode characters across platforms. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Development guidelines update:

• Added a new rule to .cursorrules requiring encoding="utf-8" to be specified for all file read and write operations.

Git workflow improvements:

• Updated .cursorrules to discourage the use of git add . and to require explicit file additions, as well as to enforce the use of conventional commit message formats.…codeError
