CI: run zero-yield jobs nightly instead of on every push

These jobs build configurations that, from May to October 2026, never
failed on master when the other push jobs passed, so they cost runner
time on every push and pull request without adding signal. Run the
whole compiler-zoo workflow, and the moved ci.yml, run-checker-merge
and windows.yml jobs, once a day; the latter in a new Nightly CI
workflow. mingw64 is a primary platform, so the MSYS2 UCRT64 build stays
on every pull request. Drop the run-checker-merge options and the plain
libFuzzer leg that other jobs already cover, and the duplicate
no-shared option in run-checker-daily.
