ci: mcpp 0.0.97 — drop the mcpp#232 index-refresh pre-step, retire per-package module smoke jobs

0.0.97 carries the default-namespace index redirect (R6), the synchronous
nasm bootstrap (#232), obj-path disambiguation (#233), spacey-defines
quoting (#234) and purview-include tracking (#235). The three module smoke
jobs (imgui-module/ffmpeg-module/opencv-module) and the tinyhttps smoke
step are deleted — the module packages are ordinary workspace members now
(next commit), so 'workspace' is the single build/run channel.
