Add ToolMetadata to OSS toolkits (#776)
Resolves TOO-388


<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Primarily metadata/dependency additions with no changes to core tool
execution paths; risk is limited to potential packaging/import issues
from the new `arcade-mcp-server` dependency.
> 
> **Overview**
> Adds `ToolMetadata` to tool decorators across the Bright Data,
ClickHouse, MongoDB, Postgres, LinkedIn, Zendesk, and Math toolkits,
specifying *behavior* (read-only/idempotency/destructive/open-world)
and, where applicable, *service domain* classification.
> 
> Updates each toolkit package to depend on `arcade-mcp-server` (plus
local `uv` source wiring) and bumps toolkit versions accordingly; minor
`__all__` ordering tweaks in Math/Zendesk are included.
