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.

+- See [readme.md](readme.md) for product context and the Python/React split.
 - Treat the Python backend as the active application backend. The React frontend is hardcoded to `http://localhost:8000`.
-- Treat `rust_backend/` as an experimental rewrite. It runs separately on `127.0.0.1:8080` and is not a drop-in replacement for the Python backend.

 - The Python backend has no checked-in dependency manifest. Before running it, confirm the local environment already has the required packages plus the EVE auth/cache files and CSV map data under `backend/data/`.
 
 ## Architecture

 - `backend/src/esi/` owns ESI auth, character location, waypoint updates, and other live API side effects.
 - `backend/src/graph.py`, `loader.py`, `market.py`, `arbitrage.py`, `pathfinder.py`, and `route.py` form the route-planning and market-analysis pipeline.
 - `frontend/src/` uses small function components. `usePolling.js` and `useSSE.js` own long-lived network subscriptions; display components render the returned payloads.
-- `rust_backend/src/main.rs` is a thin Actix entrypoint. `manager.rs` owns shared state and polling, `eve_service.rs` wraps `eve_api.rs`, and `pathfinding/` plus `market/` stay modular.
 
 ## Repo-Specific Conventions
 
-- Preserve the current port split unless the task is explicitly a migration: frontend `:3000`, Python backend `:8000`, Rust backend `:8080`.
+- Preserve the current port split: frontend `:3000`, Python backend `:8000`.
 - Keep external API calls and UI side effects out of the route-planning and market-analysis modules.
 - Prefer typed models, named thresholds/constants, and small transformations over ad hoc inline logic in backend algorithms.
-- When changing the Rust backend, do not assume Python endpoint parity. Add routes, SSE or polling support, and CORS explicitly before wiring the frontend to it.
-- Be cautious about local-only runtime dependencies: Python expects ESI auth/cache state plus CSV map data under `backend/data/`; Rust expects OAuth env vars and `token.json`.
