fix(generator-networks-creator): normalize zero viewport dimensions

[sk8kpwhrjt-creator]

Addresses #6.

@algora-pbc /claim #6

Summary

This fixes the zero viewport dimensions reported in #6 at the training-record preprocessing layer without dropping the affected records from the dataset.

The previous direct schema-tightening approach is technically correct for the final record shape, but reviewer feedback on a similar PR noted that rejecting zero innerWidth / innerHeight / clientWidth / clientHeight values removes most of the current training snapshot. This patch keeps the stricter final schema while first normalizing zero viewport fields from the same record's surrounding screen dimensions:

• derive innerWidth from min(screen.width, outerWidth) when the collected value is zero
• derive innerHeight from min(availHeight, outerHeight) when the collected value is zero
• derive clientWidth / clientHeight from the normalized inner viewport when the collected values are zero
• keep genuinely unfixable records rejected by the schema

That prevents zero viewport dimensions from reaching future generated networks while preserving otherwise useful records collected from hidden/embedded contexts.

Validation

• pnpm exec vitest run test/generator-networks-creator/record-schema.test.ts test/generator-networks-creator/generator-networks-creator.test.ts
• pnpm exec tsc --noEmit -p tsconfig.json
• pnpm --filter generative-bayesian-network compile && pnpm --filter generator-networks-creator compile
• pnpm exec prettier --check packages/generator-networks-creator/src/record-schema.ts test/generator-networks-creator/record-schema.test.ts
• git diff --check

Note: pnpm --filter generator-networks-creator build reaches TypeScript compilation, but the workspace build script then uses Unix cp, which is not available in this Windows environment. I validated the compile scripts directly instead.

As mentioned under #544 , the right solution is to fix the fingerprint collection script.

Closing this PR now. Thank you for your contribution anyway!
