Future Work for Repo Assist

• Issue Mishandling of some complex collections #2779 multiline-string-in-list soundness bug: still open; fix requires detecting embedded newlines and adding semicolons.
• Issue Idempotency problem: IndentSize = 2 broke offside rule #2740 (|> after match in lambda body): root cause in genMultilineInfixExpr atCurrentColumn; careful fix needed.
• Issue Unicode leads to incorrect indentation #2945 (Unicode combining characters): root cause confirmed — String.length in Context.fs; needs grapheme-cluster counting.
• NUnit update (4.2.2→4.5.1): blocked by Is.EqualTo overload ambiguity in EditorConfigurationTests.fs.
• NuGet Dependabot: previously tried (PR Remove nuget #3062) and reverted because project has packages.lock.json files. Do not retry.
