Summary: This PR adds new client methods for credits, guard, and skill growth endpoints to the Registry Broker client. The implementation includes:

• Credits: getCreditsBalance, getCreditProviders, createHbarPurchaseIntent
• Guard: getGuardSession, getGuardEntitlements, getGuardBillingBalance, getGuardTrustByHash, resolveGuardTrust, getGuardRevocations, syncGuardReceipts
• Skills: getSkillStatus, getSkillStatusByRepo, getSkillConversionSignalsByRepo, uploadSkillPreviewFromGithubOidc, getSkillPreview, getSkillPreviewByRepo, getSkillPreviewById, getSkillInstall, recordSkillInstallCopy, quoteSkillPublishPreview

Also includes security improvement to createEphemeralKeyPair using Web Crypto API fallback, and Node.js getBuiltinModule support in dynamic-import utilities.

All new functionality appears well-tested and follows existing patterns in the codebase.

Code Review

This pull request expands the RegistryBrokerClient with new functionalities for credits, guard services, and skill management, including API methods and corresponding Zod schemas. It also refactors secure random byte generation and internal module loading. Review feedback suggests refactoring repeated validation logic into a shared helper, enhancing type safety in schemas by replacing unknown types with specific definitions, and moving internal helper declarations outside of functions for better code organization.
