Subject: fix(elisp): gitignore the full Claude tooling footprint

The bundle tracked .claude/rules, CLAUDE.md, and githooks/, ignoring only the personal overrides. For a code project, especially a third-party package checkout, the whole Claude footprint should stay local: install and sync deliver it, so it shouldn't land in the project's history. gitignore-add.txt now ignores .claude/, CLAUDE.md, and githooks/ next to the elisp build artifacts.

I also added install-lang.bats, which the bundle had no test for. It covers the landed footprint and the gitignore set.
