Add dev extension builds via rolling GitHub Releases

On CI builds (push to main), publish unsigned extension binaries to
GitHub Releases with a rolling {ext-id}-dev tag. This gives internal
users access to latest main branch builds without waiting for a release.

- Add publish-extension-dev.yml stage (BuildAndTest → package → GitHub Release)
- Wire into release-azd-extension.yml for IndividualCI/BatchedCI builds
- Add static registry-dev.json with 0.0.0-dev version, no checksums
- Skip signing for dev builds to simplify pipeline

Usage:
  azd ext source add -n dev -t url -l <registry-dev-url>
  azd ext install azure.ai.agents --source dev --force

Closes #7317
