Update Aztec to v4.0.0-devnet.2-patch.1

- Bump aztec-nr tag in Nargo.toml
- Bump all @aztec/* packages in package.json
- Replace @aztec/test-wallet (removed) with @aztec/wallets + @aztec/wallet-sdk
- Add @aztec/constants and @aztec/entrypoints dependencies
- Migrate TestWallet → EmbeddedWallet across all TS files
- Fix registerSender() calls (now requires alias argument)
- Fix Noir debug_log import: oracle::debug_log → oracle::logging
- Update config JSON files, Dockerfile, CI workflow, and README
- Simplify multiple_wallet.ts (EmbeddedWallet handles PXE stores internally)
- Update AGENTS.md with accurate testing and setup instructions
- Fix README: install instructions, env var names, test descriptions

All tests pass: 16 Noir TXE + 16 TypeScript E2E.

 # Repository guidelines for Codex agents
 
-This repository contains TypeScript scripts and Noir contracts for the Aztec local network.
+This repository contains TypeScript scripts and Noir contracts for the Aztec network.
 Follow these guidelines when contributing:
 
 ## Setup
 - Use **Node.js v22** with Yarn.
 - Install dependencies with `yarn install`.
-- Start the Aztec local network using `aztec start --local-network` before running tests or scripts.
+- The Aztec CLI (`aztec`) must be installed at the version matching `Nargo.toml` and `package.json`.
+- Start the Aztec local network with `aztec start --local-network` before running E2E tests or scripts. This is **not** needed for compilation or Noir unit tests.
+- After restarting the local network, always run `rm -rf ./store` to clear stale PXE data.
 
 ## Development
+- This is an ESM project (`"type": "module"` in `package.json`).
 - Compile contracts with `yarn compile` and generate TypeScript artifacts with `yarn codegen`.
 - Use four spaces for indentation in TypeScript and scripts.
 - Do not commit generated artifacts (`src/artifacts`, `target`, or `store` folders).
+- Never edit `src/artifacts/PodRacing.ts` directly; it is generated by `yarn codegen`.
+- To target devnet instead of local network, set `AZTEC_ENV=devnet` (e.g. `AZTEC_ENV=devnet yarn deploy`).
 
 ## Testing
-- Run `yarn test` and ensure it passes before committing.  This runs both the TypeScript tests and Noir tests.
+There are two independent test systems:
+- **Noir TXE tests** (`yarn test:nr`): Run in the TXE simulator, no network required.
+- **TypeScript E2E tests** (`yarn test:js`): Require a running local network.
+- `yarn test` runs both. Ensure tests pass before committing.
 
 ## Pull Requests
 - Use clear commit messages and provide a concise description in the PR body about the change.
 - Mention which tests were executed.
