Merge origin/main into feat/decompose-module

Keeps the implemented-module README over main's placeholder, keeps PSModuleTest.Tests.ps1 removed (replaced by Confluence.Tests.ps1), applies the Pester 6.x requirement from #16 to Confluence.Tests.ps1, and picks up the Process-PSModule workflow bump to v5.5.7.
