feat: initialize rcmate project

Introduce rcmate, a Terminal User Interface (TUI) designed to automate,
monitor, and manage rclone synchronization tasks.

Key features included in this initial baseline:
- Interactive TUI built with `ratatui` for a fast, keyboard-driven
  experience.
- Support for multiple sync modes: sync, bisync, copy, and move.
- Real-time progress tracking via the rclone Remote Control (RC) API.
- Smart file handling that translates single-file operations to
  directory operations.
- Highly configurable TOML-based setup for sync pairs, paths, and
  filters.
- CLI argument overrides for rclone binaries, configs, and log levels.

Additionally, this commit establishes the project foundation:
- Set up GitHub Actions CI/CD for cross-platform builds and automated
  releases.
- Configured dual-licensing under MIT and Apache-2.0.
- Added comprehensive README documentation and usage instructions.
