chore(deps): drop unused packages, reclassify dev-only deps

[alejoamiras]

What

Manifest-only dependency trim — zero code changes. Resolved packages in yarn.lock drop from 743 to 668.

Removed (3 direct deps)

• @aztec/protocol-contracts — zero imports anywhere in the repo (src, scripts, benchmarks, tests, workflows, generated artifacts). Remains available transitively via aztec.js/pxe/wallets.
• @commitlint/cli + @commitlint/config-conventional — never invoked: no commitlint config file exists, no commit-msg hook (.husky/ contains only pre-commit), no CI reference.

Reclassified runtime → dev

scripts/build-package.sh publishes only dist/artifacts, target, README and LICENSE — the only package imported by shipped code is @aztec/aztec.js (via the generated artifact bindings). Everything else is exercised solely by unpublished scripts/, benchmarks/, and src/ts/test/, so it moves to devDependencies: @aztec/accounts, @aztec/noir-contracts.js, @aztec/pxe, @aztec/stdlib, @aztec/wallet-sdk, @aztec/wallets, @aztec-foundation/aztec-benchmark, commander, dotenv.

No install-behavior change: every consumer (CI included) runs a full yarn install --frozen-lockfile; nothing installs production-only.

Validation

• yarn install regenerates the lockfile cleanly; yarn install --frozen-lockfile passes (CI parity)
• Grep-audited every removed/moved package for imports (incl. subpaths, require, dynamic import()) across src, scripts, benchmarks, tests, workflows, and generated artifacts

Notes for reviewers

• The Dependabot count will barely move: the flagged packages (undici, axios, vite, ws, esbuild, protobufjs) are ~96% transitives of the @aztec/* SDK and vitest→vite, not direct choices here.
• Out of scope, observed while auditing: build-package.sh strips .dependencies from the published package.json, so consumers never get @aztec/aztec.js declared even though shipped dist/artifacts/*.js imports it — works today only because consumers already install the Aztec SDK. Worth a follow-up.
