📦 Adding a New Firmware Version

One command, from this directory. It runs a full idf.py build, copies all five flash artifacts, computes hashes, and regenerates both manifests. 

.\deploy.ps1 -Version "X.Y.Z" -Notes "What changed"

It refuses to publish any artifact older than an input it is built from — a partition table that disagrees with partitions.csv, or a SPIFFS image older than the web UI. Those ship a board that boots wrong rather than failing loudly, so the check is a hard failure. See README.md for details.
