docs(languages): tighten elisp coding and testing rules

Two audit fixes. elisp.md's "prefer Write over Edits" advice was tool-specific. It's now framed around intent: edit cohesively, then run paren and byte-compile checks immediately, whatever the editing mechanism. elisp-testing.md gains batch-mode reproducibility (emacs --batch as source of truth, no interactive state, no blocking prompts), state isolation (temp user-emacs-directory, explicit load-path, declared deps only), and byte-compile/native-comp warning handling, with native-comp gated on availability and kept opt-in.
