Run dev on host Node 16 and add deploy patch script

Switch make install/run/build/db-* off docker compose onto the host's
Node (via nvm + .nvmrc). better-sqlite3 7.6.2 doesn't build against
Node 20, and the Dockerfile was still pinned to node:20 while the
rest of the project was downgraded to Node 16 in the Win7 bundle
commit; host execution avoids that mismatch.

Also adds scripts/make-patch.sh (make patch) to produce a small
build-only update zip for an already-installed Win7 target, ignores
dist/, and points start.bat at the installed Chrome PWA shortcut
instead of opening a normal browser tab.

+
+Как установить обновление:
+
+  1. Закройте чёрное окно "start.bat", если программа запущена.
+
+  2. Распакуйте этот архив в папку C:\\avtoambor\\
+     (туда же, где лежат install.bat и start.bat).
+     Windows спросит, заменить ли существующие файлы — ответьте "Да"
+     (или "Заменить файлы в папке назначения").
+
+  3. Снова запустите start.bat двойным щелчком.
+
+Если после обновления программа не запускается — напишите Давиду.
