refactor: migrate from Go to Rust implementation

[Yuukadesu]

No description provided.

Are there any usage documents explaining how to create functions and how to trigger them?

I ran into the following error while using the CLI:

error: unexpected argument '--host' found

Usage: cli [OPTIONS]

For more information, try '--help'.

Could you help take a look at this?

The issue has been fixed.

Pull request overview

Migrates the project’s primary implementation from the legacy Go codebase to a Rust-based workspace, while also refreshing packaging, documentation, and example processors.

Changes:

• Removed Go-based server/operator/runtime implementation, CI, tooling, and related SDK/helpers.
• Added Rust workspace (server + CLI) plus container packaging, compose environment, and updated configuration.
• Introduced new examples (Python processor + Go WASM processor) and expanded end-user documentation.
