feat(vscode-extension): route DA workflows to WIQD

[llhmm01 (llhmm01)]

Summary

• route Declarative Agent creation and lifecycle guidance through WIQD
• keep ATK routing for Custom Engine Agents, bots, tabs, message extensions, Playground, Teams runtime, and backend compute
• prioritize DA manifest markers over m365agents.yml, while keeping schema-only questions local
• add focused routing evals and a packageable Declarative Agent fixture

Parent feature: https://msft.ghe.com/substrate/wiqd/issues/1761
ATK tracking issue: https://msft.ghe.com/substrate/wiqd/issues/3249

Validation

• wiqd --version, wiqd auth status, and wiqd doctor
• verified WIQD 0.14.0 command options for create, validate, package, provision, share, publish, delete, and action creation
• ran wiqd agent validate and wiqd agent package against the DA fixture; package generated successfully
• focused Waza DA evals: 3/3 passed with aggregate score 1.00
  • DA markers take precedence over m365agents.yml
  • schema-only DA questions do not require WIQD or ATK
  • DA creation uses WIQD without ATK fallback
• Teams bot regression eval passed and continued to use ATK
• parsed all changed YAML/JSON, verified Markdown links and fixture references, and ran git diff --check
• confirmed no changes under packages/fx-core, packages/cli, packages/vscode-extension/src, or packages/vscode-extension/package.json

Notes

• The full credentialed Waza configuration was not run locally because the CI M365/Azure environment variables are unavailable. The configured claude-sonnet-4.6 model was also unavailable locally, so focused runs used gpt-5.4.
• The existing Custom Engine Agent eval continues to route correctly to ATK and reject WIQD. Its root-only m365agents.yml file assertion remains sensitive to whether the generated project is placed in a subdirectory; this is unrelated to the routing change.
