chore: housekeeping — env docs, ownership metadata, dead config

[alejoamiras]

What

Repo housekeeping:

• .env.example: previously documented VERSION and BASE_PXE_URL, which nothing reads. Now documents the vars the code actually uses: NODE_URL (tests/benchmarks), AZTEC_NODE_URL and SIGNING_KEY_SECRET (deploy script).
• LICENSE: appends Copyright (c) 2026 Aztec Foundation (Wonderland's line retained per MIT practice); package.json author updated to match the @aztec-foundation npm scope.
• build-package.sh: stops deleting a .jest key that doesn't exist (repo uses vitest).
• deploy-config.ts: replaces // TODO: add mainnet-alpha with an explicit statement that deployments are dev-network-only by design.

Note: the deploy tooling and deployments.json intentionally stay — the published npm package ships deployments.json and external projects consume those testnet addresses.

Validation

bash -n on the script; no behavior changes.
