2# webhook.sh — Smart auto-deploy for lith
3# Called by POST /lith/deploy (from GitHub push webhook)
4#
5# Strategy:
6# 1. git pull
7# 2. Check which files changed
8# 3. If only static frontend files changed → done (Caddy serves from disk)
9# 4. If backend functions or lith/ changed → npm install if needed, restart lith
10# 5. If Caddyfile changed → reload caddy
11#
12# This means most frontend pushes deploy instantly with zero downtime.
