chore: add Claude Code ruleset via ~/code/rulesets install-elisp

Installs the Elisp ruleset from the rulesets repo:

  - CLAUDE.md (project instructions template)
  - .claude/rules/ (testing, verification, elisp, elisp-testing)
  - .claude/hooks/validate-el.sh (check-parens + byte-compile + run
    matching tests on every .el edit via PostToolUse)
  - .claude/settings.json (permission allowlist + hook wiring)
  - githooks/pre-commit (secret scan + staged-file paren check)

core.hooksPath set to githooks/ so the pre-commit activates automatically.
Hooks use \$CLAUDE_PROJECT_DIR with a script-relative fallback, so a
fresh clone works without path edits.

.gitignore extended with personal-override entries (settings.local.json,
.cache/) and byte-compile artifacts (*.elc, *.eln).
