- Added `data_download_list` field to `ComponentConfig` struct in `component.rs`.
- Implemented processing of `data_download_list` in the `PackageManager` to download files asynchronously in `facade.rs`.
- Updated `installer.rs` to initialize `data_download_list` for various components.
- Refactored `download_file` function in `utils.rs` to return `anyhow::Error` for better error handling.
Implement a new method `start_all` in `BootstrapManager` to start all
components using the `PackageManager`.
This method creates a new `PackageManager` instance and uses it to start
each component in a predefined list.
--- Add remove_local for PackageManager
Remove component specific code
The specific code for component 'tables' has been removed from the
`remove_local` method in `PackageManager`.
The method now simply removes the binary directory for the component.
--- Implement start for PackageManager
Add a new method `start` to `PackageManager` to start a component.
This method takes a component name as an argument and uses the
`exec_cmd` for that component to spawn a new process.
If the component is not found, it returns an error.
Implement core package manager with component configuration, installer
logic, OS detection, and a command‑line interface for install, remove,
list, and status operations.
