[dotnet-code] Consolidate agent host request dispatch internals

[github-actions]

Summary

Consolidates the duplicated hosted-agent request tracking and dispatch loops used for tool approval requests and unterminated function calls into one unexported helper. This keeps the Go hosting internals structurally closer to the .NET host option model where request interception is handled through common host behavior, while preserving the existing public Go config shape and dispatch semantics.

.NET Reference

• dotnet/src/Microsoft.Agents.AI.Workflows/AIAgentHostOptions.cs - host options describing intercepted user-input requests, intercepted unterminated function calls, forwarded messages, and agent response/update emission.

Public API and Behavior

No public Go API changed. No intentional behavior change was made.

Tests

• go test ./workflow/agentworkflow

Notes

Rejected sampled candidates:

• dotnet/src/Microsoft.Agents.AI.Workflows/SwitchBuilder.cs / Go workflow edge dispatch: already covered by open PR [dotnet-code] Consolidate workflow edge connection construction #799.
• dotnet/tests/Microsoft.Agents.AI.UnitTests/AgentSkills/FilteringAgentSkillsSourceTests.cs / Go skills lookup: already covered by open PR [dotnet-code] Consolidate skill member lookup internals #800.
• dotnet/tests/Microsoft.Agents.AI.UnitTests/Compaction/ChatReducerCompactionStrategyTests.cs / Go compaction internals: overlapped active compaction cleanup PRs [dotnet-code] Consolidate compaction included group helpers #794, [dotnet-code] Consolidate compaction group inclusion checks #795, and [dotnet-code] Consolidate compaction non-negative normalization #796.
• dotnet/src/Microsoft.Agents.AI.Workflows/Checkpointing/CheckpointManagerImpl.cs / Go checkpoint manager: inspected, but no smaller safe structural improvement was preferable to the hosting cleanup.
