chore: remove all Gumroad references

- web/learn.html: replace "Buy on Gumroad" buttons with "Start Course"
  links pointing at the open-source course content on GitHub; drop the
  bundle purchase block and per-course price tags that existed only to
  sell Gumroad versions.
- education/README.md: rewrite to treat the courses purely as open
  source — no pricing, no Gumroad funnel, no "paid guided experience"
  tier. What's in the repo is what you learn from.
- .gitignore: drop now-redundant gumroad/ + GUMROAD_LISTINGS entries
  that referenced content already removed earlier.

All courses remain fully available and free to read in /education.
