Add disabled flags to project config

[imrishabh18]

Summary

• add pcbDisabled and schematicDisabled to the exported ProjectConfig type
• include both flags in the projectConfig Zod schema
• add parser coverage for true and false values
• regenerate the checked-in README documentation

Why

Consumers that load tscircuit.config.json currently need to redeclare these fields locally even though both already exist on PlatformConfig. Exposing them through ProjectConfig gives JSON project configuration a shared source of truth.

Impact

Packages such as @tscircuit/eval can extend ProjectConfig and consume the rendering-disable flags without duplicating their definitions.

Validation

• bun test tests (374 passing)
• bun run typecheck
• bun run format:check
• bun run build
• all repository-required generation scripts
