Pillar Skill

Provides Pillar smart wallet operations in two modes:

• pillar.ts — Browser-handoff mode. Creates an operation on the Pillar backend, opens the Pillar frontend in the user's browser for signing, then polls for the result. Requires the user to be logged in at pillarbtc.com.
• pillar-direct.ts — Agent-signed direct mode. Generates and manages a local secp256k1 signing keypair. Signs SIP-018 structured data locally, submits directly to the Pillar backend API. No browser needed; gas is sponsored by the backend.
