[codex] Add workflow-preset integration Actions

[bigsmartben]

Summary

• Add a workflow-preset-release repository_dispatch entrypoint for validating released workflow-preset artifacts.
• Strengthen community smoke coverage for workflow-preset inventory, command registration, resolver output, and template resolution.
• Add tests that keep bundled catalog metadata and release payload contracts aligned.

Validation

• uv run pytest tests/test_presets.py -k "workflow_preset or bundled_preset" -v
• uv run pytest tests/integrations/test_cli.py -k "community_extensions_and_workflow_preset_auto_installed or workflow_preset_registers" -v
• uv run pytest tests/integrations -k "complete_file_inventory" -v
• uv run pytest
• workflow YAML parse for .github/workflows/community-smoke.yml and .github/workflows/workflow-preset-integration.yml

Remove nonexistent tasks template check

This check makes the new release-validation workflow fail for the current workflow-preset artifact: the bundled preset manifest/source tree contains templates/plan-template.md and the behavior templates, but no templates/tasks-template.md (repo-wide search only finds this new workflow reference). Any workflow-preset-release dispatch for a valid release shaped like the bundled preset will exit here before verifying the command registration.
