Check initial bundle size

[CodeWithMa]

Building emits this warning:

▲ [WARNING] bundle initial exceeded maximum budget. Budget 500.00 kB was not met by 161.67 kB with a total of 661.67 kB.

[CodeWithMa]

Investigated bun run build warning: Initial total 662.97 kB raw / 140.15 kB transfer vs budget 500kB warning / 1MB error in angular.json:41.

No user impact. Error budget not hit. Transfer (gzipped) 140kB is what Vercel users download - well within budget. Electron is local files, so irrelevant.

Root cause: zod 332kB (52%) of main (src/app/domain/storage-schema.ts:1 -> src/app/services/storage.service.ts:5 -> src/app/app.config.ts:18 via provideAppInitializer). Of that, ~201kB is zod/v4/locales/* - all 50+ locales bundled though only en is used. Known tree-shaking issue: export * as locales in zod/v4/core/index.js:9 pulls every locale even when unused. Without zod, initial would be ~330kB.

All routes in src/app/app.routes.ts:3 are already loadComponent lazy-loaded.

Decision: do nothing.

Angular's default 500kB is strict for Angular 22 + real deps. Raising warning to 700kB would silence it with 0 code churn, but keeping the warning as-is is also fine - it's not failing the build, just noise. Reverting to manual guards (pre-576ee7c) or dynamically importing zod would save ~300kB raw but adds complexity for no transfer/UX gain - not worth it (YAGNI).
Closing as won't fix. Reopen if we want to raise maximumWarning to 700kB or optimize zod later.
