Fix custom recipe pack reconciliation on repeat deploys

[sk593]

Summary

• derive custom recipe-pack identities from the compiled authored Bicep instead of a global before/after list diff
• preserve existing environment recipe packs while attaching only the exact authored packs on first and restored-state redeploys
• add composite-action regression coverage and update the Repo Radius workflow documentation

Testing

• make test-apply-custom-recipe-packs
• shellcheck .github/extension/actions/apply-custom-recipe-packs/apply-custom-recipe-packs_test.sh

Resolves radius-project/ai-extensions#323

Pull request overview

This PR updates the Repo Radius deploy workflow’s custom recipe-pack reconciliation so repeat deploys (including redeploys after state restore) deterministically attach only the recipe packs authored by the repo while preserving any recipe packs already attached to the environment.

Changes:

• Update apply-custom-recipe-packs to derive recipe-pack identities from compiled Bicep output and attach only authored packs (plus existing attached packs).
• Add a composite-action regression test suite and wire it into make test.
• Update Repo Radius workflow documentation to reflect the new reconciliation behavior and test coverage.

• The multi-pack fixture here models resources as an object keyed by resource name, but bicep build often emits resources as an array (languageVersion 1.x). Without an array-shaped fixture, the tests won't catch a regression where array output breaks pack discovery. Use an array fixture for this scenario to cover that output shape.

Two non-blocking observations on the discovery/attach path. Neither should hold up the merge — the fix itself is correct and the redeploy path is well covered. The first one would benefit from a regression test to pin the intended contract.
