* fix(railway): use npm install instead of npm ci for Railpack compat
Railpack runs the install step before source files are fully copied
into the build container, so package-lock.json isn't available when
npm ci executes. Switch to npm install --omit=dev which doesn't
require a pre-existing lockfile.
* fix(docs): add blank lines around lists in roadmap-pro.md
Auto-fix MD032 markdownlint violations (blanks-around-lists).
