Subject: feat: add per-project language bundles + elisp ruleset

Introduces a second install mode alongside the existing global symlinks:
per-project language bundles that copy a language-specific Claude Code
setup (rules, hooks, settings, pre-commit) into a target project.

Layout additions:
  languages/elisp/       - Emacs Lisp bundle (rules, hooks, settings, CLAUDE.md)
  scripts/install-lang.sh - shared install logic

Makefile additions:
  make help              - unified help text
  make install-lang LANG=<lang> PROJECT=<path> [FORCE=1]
  make install-elisp PROJECT=<path> [FORCE=1]   (shortcut)
  make list-languages    - show available bundles

Elisp bundle contents:
  - CLAUDE.md template (seed on first install, preserved on update)
  - .claude/rules/elisp.md, elisp-testing.md, verification.md
  - .claude/hooks/validate-el.sh (check-parens, byte-compile, run matching tests)
  - .claude/settings.json (permission allowlist, hook wiring)
  - githooks/pre-commit (secret scan + staged-file paren check)
  - gitignore-add.txt (append .claude/settings.local.json)

Hooks use \$CLAUDE_PROJECT_DIR with a script-relative fallback, so the
same bundle works on any machine or clone path. Install activates git
hooks via core.hooksPath=githooks automatically. Re-running install is
idempotent; CLAUDE.md is never overwritten without FORCE=1.
