parameterize quarter and Canvas course ID via site_config.py

TrevorAustin · claude · TrevorAustin · commit 1ccc53013a06 · 2026-04-03T15:29:29.000-05:00
build.py now reads site_config.py and updates all source files
(README, syllabus, lecture notes) with the current quarter name and
Canvas course ID on each build. Templates use Jinja2 globals.

Assignment-specific Canvas links replaced with course assignments
list page so they don't need per-quarter updates.
