Agent Tooling Types

Type-only exports from agent/tooling.ts — the contract between capabilities and the facade.

Type	Shape (summary)
`ToolDefinition`	`{ name; description; isReadOnly; inputSchema; call(input, ctx) }`
`ToolContext`	`{ userId; mode; origin; defaults; emit(draft) }` injected into every `call`
`ToolResult`	`{ data; paymentIntent?; submit? }`
`EmitResult`	`{ intent: PaymentIntent; submit: SubmitResult }` returned by `Xpense.emit`
`PaymentDefault`	`{ defaultAsset; caip2; address }`
`PaymentDefaultStore`	`get / set / unset` over a `PaymentDefault`

Outline only — exact field lists live in src/agent/tooling.ts.
