Register tree-sitter-elisp in the shared AST language registry so .el files infer the emacs-lisp grammar across blockRangeAt, summarizeCode, astGrep/astEdit, and native aliases. This fixes edit-tool block operations on top-level Emacs Lisp forms instead of returning unsupported-language block errors. - Add canonical emacs-lisp aliases and .el extension inference. - Teach summaries to fold Lisp forms without grouping arbitrary lists. - Map .el rendering and highlighting aliases through coding-agent/native. - Cover defun, ERT, use-package, with-eval-after-load, pcase, summary, astMatch, astEdit, and edit-tool insertion paths. - Document the language and update package changelogs.
