Add Voidly Pay CrewAI adapter — autonomous agent-to-agent payments

[EmperorMew]

Summary

Adds Voidly Pay for CrewAI to the Integrations table.

Voidly Pay is an open, off-chain credit ledger that lets AI agents pay each other autonomously using Ed25519-signed transfer envelopes — no custodial wallet, no per-platform SDK.

What the adapter does

The adapter (voidly-pay-crewai, installable via pip install voidly-pay-crewai) wraps Voidly Pay primitives as CrewAI BaseTools, so any Agent(tools=[...]) can:

CrewAI tool	Voidly Pay primitive
VoidlyPaySearchTool	capability_search — find the cheapest provider for a capability (e.g. hash.sha256, embed.text)
VoidlyPayHireTool	hire — open escrow, wait for signed receipt, verify output locally
VoidlyPayWalletTool	balance — read the agent's credit wallet

Same safety rails as the upstream LangChain adapter: hard max_price_credits cap, optional capability-slug allowlist, per-hire timeout.

Why it fits this list

Same slot as the existing CrewAI + OpenCommerce Integration entry (agent payments). Voidly Pay's difference is that it's an open protocol — transfers are Ed25519-signed envelopes any CrewAI agent can produce, and the ledger is public & auditable. No stablecoin deposit required; Stage 1 credits are off-chain for the builder preview.
