* Add C# 15 extension indexers to extension members tutorial Update the extension members tutorial to cover the C# 15 addition of extension indexers. Reframe the tutorial for C# 14 and C# 15, bump the sample to .NET 11 preview with LangVersion preview, and add an "Add extension indexers" section. The new section introduces a Path type that stores (dX, dY) offsets and adds an extension indexer whose getter computes the absolute Point at an index (from Point.Origin) and whose setter adjusts the offset at that index. Build and run verified on the .NET 11 preview SDK.

* Consolidate jump-statement diagnostics Add a new themed article, jump-statement-errors.md, covering compiler errors and warnings for the break, continue, goto, and return statements: CS0126, CS0127, CS0139, CS0153, CS0159, CS0161, CS0163, CS0469, and the new CS9393/CS9394 diagnostics for labeled break and continue (dotnet/roslyn#84271). Remove the standalone articles for the consolidated codes, add redirects to the new article, and update the compiler-messages TOC. Async/Task return diagnostics and iterator diagnostics are cross-referenced to their existing themed articles rather than duplicated here.

* Document C# 8 misc diagnostics (#54660) Consolidate the remaining C# 8 miscellaneous compiler diagnostics into themed compiler-message articles and remove them from the catch-all. New consolidated articles: - static-local-function-errors.md (CS8421) - index-range-errors.md (CS8428, CS8429) - parsing-errors.md (CS8635, CS8641) — scoped to parser/lexer-stage errors - readonly-member-errors.md (CS8656, CS8662) Added to existing articles: - attribute-usage-errors.md: CS8423 - interface-implementation-errors.md: CS8646 - nullable-warnings.md: CS8650, CS8651, CS8669 Removed all 12 codes from the sorry-we-don-t-have-specifics catch-all and added TOC entries for the new articles. Messages verified against Roslyn source. Note: the issue listed CS8556, which does not exist; the correct readonly-member warning is CS8656.

Adds CS8108, CS8112, CS8321, and merges standalone CS8422 (with redirect). - index-range-errors.md -> indexer-access-errors.md: indexer and element access. Adds CS0021, CS0154, CS0271, CS0272, CS0856, CS0857, CS1545, and merges standalone CS1546 (with redirect). - readonly-member-errors.md -> readonly-struct-errors.md: readonly struct declarations and members. Adds CS8340, CS8342. Updates TOC entries and titles for the renames, removes the added codes from the catch-all, and cross-references related diagnostics that remain in their existing articles.
