v0.1.3 — shared budgets and payment recovery

This release prevents wallet processes from spending the same budget concurrently and keeps interrupted payment outcomes conservative.

• Share spending and budget locks across processes using the same wallet database, and recheck reservations after approval.
• Keep chain statuses moving forward despite delayed RPC responses.
• Recover interrupted submissions on payment, status, and history calls. Preserve unknown outcomes and idempotency keys when RPC cannot prove whether funds moved.
• Page through invoice payment history and report incomplete searches. Search external invoices without assuming a maximum lifetime.
• Explain uncertain submissions in the README and MCP instructions.

Validation: 43 unit tests, 8 integration tests against a fresh local Solana validator, clippy with warnings denied, rustfmt, and git diff checks.

This is the agent-wallet source release. The official manus binary consumes this repository through a pinned tag; updating that binary requires a corresponding manus-pay release.
