[hard] Refactor index.ts exports to reduce surface duplication with facades

[davedumto]

Summary

index.ts re-exports items that overlap with what policy-facade.ts and x402-facade.ts already expose, creating duplicate paths to the same functionality.

Requirements

• Audit index.ts exports against the facade modules for overlap
• Consolidate duplicated export paths into a single canonical one
• Ensure the change does not break the documented public API surface
• Add a test asserting the export list matches the intended consolidated surface
