Cmyers launchpad refactor

[cmyers-mieweb]

This pull request significantly refactors the action.yml workflow for the MIEWeb LaunchPad action, modularizing the logic for container management by delegating API calls to reusable composite actions from mieweb/opensource-server/.github/actions. The workflow is now more maintainable, robust, and easier to extend, with clearer separation of concerns for event classification, container lifecycle management, and reporting.

Key changes include:

Workflow modularization and delegation:

• Replaces in-line bash logic for container creation, deletion, and status querying with calls to reusable composite actions: get-container, create-container, and delete-container. This reduces code duplication and centralizes API interaction logic. [1] [2]

Improved event handling and classification:

• Introduces a dedicated "Classify Event" step to determine whether the workflow should manage or delete a container, based on the event type and action (e.g., branch deletion, PR closed).

Container lifecycle management:

• Splits container management into distinct phases: preparation (naming/template normalization), locating existing containers, planning create/recreate/delete actions, and executing them via composite actions. Adds explicit planning logic to decide when to delete and/or create containers. [1] [2]
• Adds robust handling for container deletion on branch deletion or PR closure, including checks for container existence and clearer reporting if no container is found.

Status reporting and error handling:

• Refactors status querying and reporting to use the composite get-container action, improving reliability and simplifying error handling. Adds a dedicated reporting step with clearer output and error messages if containers are not found or not running.

Documentation and metadata:

• Updates the action description and adds detailed comments explaining the LaunchPad orchestrator’s purpose and pinning strategy for composite actions.
