Writes a file to the local filesystem.

Usage:

• This tool will overwrite the existing file if there is one at the provided path.${MUST_READ_FIRST_FN()}
• Prefer the Edit tool for modifying existing files — it only sends the diff. Only use this tool to create new files or for complete rewrites.
• NEVER create documentation files (*.md) or README files unless explicitly requested by the User.
• Only use emojis if the user explicitly requests it. Avoid writing emojis to files unless asked.
