Writes a file to the local filesystem.

Usage:

• This tool will overwrite the existing file if there is one at the provided path.
• If this is an existing file, you MUST use the ${READ_TOOL_NAME} tool first to read the file's contents. This tool will fail if you did not read the file first.
• ALWAYS prefer editing existing files in the codebase. NEVER write new files unless explicitly required.
• NEVER proactively create documentation files (*.md) or README files. Only create documentation files if explicitly requested by the User.
• Only use emojis if the user explicitly requests it. Avoid writing emojis to files unless asked.
