build(core): adopt fork and remove experimental rust backendHEADmaster

- Added a 2026 copyright statement under the original creator's in `license.md` to properly establish new fork logic.
- Updated `readme.md` to explicitly state this repository is a maintained fork.
- Eliminated the `rust_backend/` directory, Actix codebase, and its associated launch configurations.
- Purged all references specifying a Python/Rust/React tri-split from `AGENTS.md` and the frontend `.instructions.md` configuration.
