fix: build libs in CI job, remove noPropertyAccessFromIndexSignature

[Danziger]

Summary

CI job will now run typecheck on all projects, including libs, to avoid PRs checks from passing but a library publish step from failing shortly after.

Detailed list of changes:

Root scripts & Nx

• package.json — typecheck script is now nx run-many -t typecheck --all --parallel=4 so CI and local runs typecheck all projects with a typecheck target, not only the CowSwap app.
• nx.json — defaultBase is set at the root; sync.disabledTaskSyncGenerators includes @nx/js:typescript-sync to avoid conflicting auto-generated TS project sync.
• tsconfig.json (repo root) — added to avoid nx cli errors when running some commands

Removed noPropertyAccessFromIndexSignature

Dropped from these tsconfig.json files so process.env.NODE_ENV and similar can use dot access without TS4111, without maintaining per-lib ProcessEnv augmentations (this is what broke the previous publish process run).

• libs/abis/tsconfig.json
• libs/hook-dapp-lib/tsconfig.json
• libs/permit-utils/tsconfig.json
• libs/ui-utils/tsconfig.json
• libs/wallet-provider/tsconfig.json
• libs/widget-lib/tsconfig.json

Explicit typecheck targets in project.json

Overrides use nx:run-commands with tsc --noEmit -p … (or a no-op where noted) so inference does not rely solely on tsc --build --emitDeclarationOnly in problematic graphs:

Project	Notes
apps/cowswap-frontend	tsc --noEmit -p apps/cowswap-frontend/tsconfig.app.json
apps/explorer	tsc --noEmit -p apps/explorer/tsconfig.app.json
apps/widget-configurator	tsc --noEmit -p apps/widget-configurator/tsconfig.app.json
apps/cowswap-frontend-e2e	tsc --noEmit -p apps/cowswap-frontend-e2e/tsconfig.json
libs/ui	tsc --noEmit -p libs/ui/tsconfig.lib.json
libs/tokens	tsc --noEmit -p libs/tokens/tsconfig.lib.json
libs/snackbars	tsc --noEmit -p libs/snackbars/tsconfig.lib.json
libs/multicall	tsc --noEmit -p libs/multicall/tsconfig.lib.json (see viem/ox below)
libs/balances-and-allowances	tsc --noEmit -p libs/balances-and-allowances/tsconfig.lib.json (same)
libs/wallet	command: true — intentional placeholder until viem/ox upstream typing issues are addressed

Other libraries still use the Nx @nx/js inferred typecheck where appropriate (tsc --build --emitDeclarationOnly).

viem / ox and multicall-style libs

For libs/multicall and libs/balances-and-allowances, tsconfig.lib.json sets:

• moduleResolution: "bundler" — resolves ox/viem through package exports to .d.ts, not node_modules .ts sources.
• outDir: "../../dist/out-tsc" — declaration output (when emitted) goes under dist/, not next to src/.

Typecheck uses tsc --noEmit so declaration maps do not pull ox sources into the check.

outDir on library tsconfig.lib.json (declaration emit)

Libraries that enable declaration: true now set outDir: "../../dist/out-tsc" (or ../../dist/out-tsc/wallet for wallet) so tsc --build --emitDeclarationOnly does not write .d.ts beside src/. Touched libs include (non-exhaustive): abis, analytics, assets, balances-and-allowances, common-const, common-hooks, common-utils, core, ens, multicall, etc.

.gitignore (safety net)

Ignores accidental emit artifacts if someone runs tsc without the intended config:

• libs/**/src/**/*.d.ts with !libs/wallet/src/types.d.ts
• **/jest.config.d.ts
• **/tsconfig*.tsbuildinfo

Shared ambient types

• types/cow-protocol-ambient.d.ts — declare module for @cowprotocol/assets/*, @cowprotocol/assets/fonts/* (nested font paths), *.svg, *.png.
• libs/wallet/src/types.d.ts — /// <reference path="../../../types/cow-protocol-ambient.d.ts" /> plus existing Window.ethereum / @metamask/jazzicon declarations.
• libs/ui/tsconfig.lib.json — includes ../../types/cow-protocol-ambient.d.ts in files so libs/ui tsc --noEmit resolves font imports.

To Test

The CI job in Github should now run typecheck on all projects.
