feat: add Bolyra action provider for ZKP agent identity

[saneGuy]

Summary

Adds bolyraActionProvider with two actions for ZKP-based agent identity verification:

• create_identity_proof — Generate a credential proving this agent's identity and permissions using zero-knowledge proofs
• verify_identity_proof — Verify another agent's proof envelope and optionally check required permissions

Complements the ERC-8004 provider: ERC-8004 handles on-chain registry identity, Bolyra handles off-chain ZKP portable identity with privacy-preserving proofs. Network-agnostic (off-chain ZKP).

Files added:

• typescript/agentkit/src/action-providers/bolyra/bolyraActionProvider.ts — provider class
• typescript/agentkit/src/action-providers/bolyra/schemas.ts — Zod input schemas
• typescript/agentkit/src/action-providers/bolyra/bolyraActionProvider.test.ts — unit tests
• typescript/agentkit/src/action-providers/bolyra/index.ts — re-exports
• typescript/agentkit/src/action-providers/bolyra/README.md — documentation

Uses @bolyra/sdk as a lazy-loaded optional peer dependency.

WISHLIST.md alignment

Addresses aspects of:

• "Interact with smart wallet/spend permissions" — permission-scoped credentials
• "Claude MCP support" — Bolyra's MCP packages complement this provider
• "Integrate with commerce rails for agent payments" — identity verification before payment

Test plan

• Constructor throws when operatorSecret is missing
• Accepts bigint and hex string secrets
• create_identity_proof generates valid proof with permissions
• create_identity_proof rejects invalid permission strings
• verify_identity_proof passes for valid proofs
• verify_identity_proof fails for invalid proofs
• verify_identity_proof checks required permissions and reports missing ones
• Error message when @bolyra/sdk is not installed
• supportsNetwork returns true for all networks

• @bolyra/sdk on npm
• Bolyra GitHub
• Live demo
