Keep public toolsets skill-first

[louis4li]

Summary

• Move Studio provisioning/member/query/bind/schedule tool sources out of workspace.default into explicit studio.local.
• Keep Lark/channel/default paths on the sanitized workspace toolset instead of ambient Studio-local IAgentToolSource registrations.
• Add composition assertions covering workspace.default, lark.self_notify, global agent tool sources, channel reply sources, and studio.local.

Test plan

• dotnet test test/Aevatar.Capabilities.Tests/Aevatar.Capabilities.Tests.csproj --filter MainnetHostCompositionTests --nologo --verbosity minimal
• dotnet test test/Aevatar.AI.Tests/Aevatar.AI.Tests.csproj --filter NyxIdChatServiceCollectionExtensionsTests --nologo --verbosity minimal
• bash tools/ci/architecture_guards.sh incomplete locally: Python failed loading pyexpat/libexpat in project_reference_layer_guard.py after earlier guards passed.

Fixes #2975
