Summary

This PR refactors the ConsumerProcess class in the async-queue component by renaming the $queue property to $pool to better reflect its purpose as a connection pool identifier rather than a queue name.

Changes

• Renamed protected property $queue to $pool in ConsumerProcess class
• Added backward compatibility support in the constructor to check for legacy $queue property
• Updated all references from $queue to $pool throughout the class
• Changed process name from "queue.{$queue}" to "pool.{$pool}"

Backward Compatibility

The change maintains backward compatibility by checking if the legacy $queue property exists and using its value if present. A comment has been added indicating this compatibility layer will be removed in v3.2.

Migration Path

For existing implementations extending ConsumerProcess:

Before:

class MyConsumerProcess extends ConsumerProcess
{
    protected string $queue = 'my-queue';
}

After:

class MyConsumerProcess extends ConsumerProcess
{
    protected string $pool = 'my-queue';
}

Existing code using the old $queue property will continue to work until v3.2.

Test Plan

• Verify existing consumer processes continue to work
• Test with both old $queue and new $pool property declarations
• Confirm process names are correctly generated
• Ensure driver factory receives correct pool identifier
