v4.1.0 — Wallet Check, XdToken Support, ADK Integration Docs

SDC Agents 4.1.0

Added

• catalog_check_wallet tool in CatalogToolset — check wallet balance and auto-reload settings before expensive operations (requires API key)
• XdToken support in TYPE_COMPATIBILITY mapping matrix — "token" source type maps to XdToken, "string" now also matches XdToken as fallback
• ADK integration documentation and minimal example for Google ADK tools catalog submission

Changed

• select_contextual_components expanded from 3 slots to all 9 contextual types supported by SDCStudio Assembly API (adds subject, provider, participation, protocol, workflow, acs)
• Catalog agent instruction updated to mention wallet checking capability
• CatalogToolset now exposes 6 tools (was 5)

Tests

• 201 tests passing (was 199), 2 skipped
• New tests: XdToken type compatibility, 9-slot contextual components, wallet check with/without API key

See CHANGELOG.md for full details.
