[dotnet-port-fixes] Align skill asset blocks with .NET

[github-actions]

Summary

Ported the .NET skill content behavior from microsoft/agent-framework#6672 so file-based Go skills append authoritative <available_resources> and <available_scripts> blocks to loaded skill content. Empty resource/script lists now emit explicit self-closing blocks, and scripts with schemas are represented with nested <parameters_schema> entries instead of the older <script_schemas> shape.

Upstream commit: e4b89373f1cdc2fe6a047fd74d48bf9ab74b951b (microsoft/agent-framework@e4b8937).

Ported .NET PRs

• .NET: Explicitly emit available_resources and available_scripts in skill content agent-framework#6672 - Explicitly emit available resources and available scripts in skill content.

Breaking Changes

No.

Tests and Examples

• Added/updated file-skill content tests for populated and empty resource/script blocks.
• Updated provider load-skill expectations for the explicit empty blocks.
• Ran go test ./agent/skills/....
• Ran go test ./....

Notes

Skipped microsoft/agent-framework#6759, which adds description attributes to resource/script entries, as a separate follow-up after this basic block-shape parity change. No public Go API changes were made.
