Known Hotswap Agent 2.0.2 Reloading Limitations with Grails 7+

[jamesfredley]

Issue description

Changes to configure Hotswap Agent in an existing application, including automating the download and use on hotswap-agent.jar and gragent.jar: jamesfredley/hotswap-demo@fb8386c

HotswapProjects/HotswapAgent#581 - lacks Spring Boot 3.x.x and Spring Framework 6.x.x support, although it still works to some extent

Produces a lot of error logs, while still mostly working

Reloads automatically:

• adding a controller for an existing domain
• editing a controller
• editing an existing service

Does not work without a restart:

• new domain class
• editing domain classes
• editing a service
• grails generate-all, due to order files are generated
