Add hook to require tests before git commit/push

Add a Bash hook script (.claude/hooks/require-tests-before-git.sh) that reads PreToolUse JSON from stdin, extracts tool_input.command using jq, and blocks git commit or git push operations by exiting with code 2 and printing instructions to run the test suite. Also register the hook in .claude/settings.json under a Bash matcher so the hook is invoked for relevant tool runs.
