ci: every workflow and job carries a human-readable Russian name

Owner decision (chat, 2026-08-27): the running check's name must say what it
does, in Russian. Scripts locate workflows by file name (release-gate.mjs ->
validate.yml), so display names are free; job ids and needs are untouched.
The same content is cherry-picked to main because release workflows execute
from the default branch and process.yml must stay identical in main and dev.
