We will be adding some product analytics toolkits in the near future
<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Low Risk**
> Low risk: adds a new `ServiceDomain` enum value and bumps the package
version, with minimal behavioral impact beyond any downstream enum
matching/serialization expectations.
>
> **Overview**
> Adds `ServiceDomain.PRODUCT_ANALYTICS` (`"product_analytics"`) to tool
metadata classification to support upcoming product analytics
integrations.
>
> Bumps `arcade-core` version from `4.5.0` to `4.6.0`.

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> **Medium Risk**
> Tightens validation on tool metadata, which may break existing tools
that relied on non-JSON-serializable `extras` values or keys; changes
are localized and well-covered by tests.
>
> **Overview**
> Adds **JSON-safety enforcement** for `ToolMetadata.extras`: top-level
keys must be strings at model construction, and `validate_for_tool()`
now recursively rejects non-JSON-native values (including non-finite
floats) with path-rich `ToolDefinitionError` messages.
>
> Expands tests to cover valid/invalid nested `extras` cases and
error-message quality, and bumps `arcade-core` version to `4.5.0`.
