#!/usr/bin/env bash
# setup-dev.sh — one-time developer environment setup.
#
# Run once after cloning:
#   chmod +x setup-dev.sh && ./setup-dev.sh
#
# What it does:
#   1. Configures git to use .githooks/ (activates pre-commit / pre-push).
#   2. Detects a mismatched global git identity and sets a repo-local one.
#   3. Registers the global email as blocked in .git/config so the hooks
#      catch it — no email is hardcoded in the repo itself.
#   4. Creates a Python venv and installs test dependencies.
