Subject: [PATCH] fix(phys9): cache-bust phys9_*.js + phys.js (?v=20260530)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

KaTeX-фикс в phys9_ch1_widgets.js (delimiters $...$ в renderMathInElement) и
исправление ловушки $(v_1+v_2)/2$ в §7 «Средняя скорость» уже были в HEAD
(коммит 5b075cd), но из-за агрессивного браузерного кеша JS-файлов пользователи
продолжали видеть старую версию: формулы как raw текст, ловушка как
($v_1+v_2)/2$ с битым синтаксисом.

HTML уже имеет no-cache meta-теги, но они не контролируют кеш связанных JS.
Добавляю query-string ?v=20260530 к phys.js и phys9_*.js на 5 страницах глав.
