Simplify Pages workflow and tidy README

Remove workflow concurrency settings and consolidate multiple render/organize steps into a single Render website step that invokes bash build.sh. This replaces per-course quarto render loops and the separate site-organizing step to simplify CI logic and delegate build details to build.sh. Also remove an obsolete checklist item from README (生物信息学算法（规划）).
