fix: CI workflows, ruff config, README rewrite

- Configure ruff per-file-ignores for educational codebase (974 → 0 violations)
- Fix mkdocs deploy: pin deps, move config to avoid docs_dir restriction, remove social plugin
- Rewrite README with personal story: "I Don't Know Python. So I Built This."
- Close issues #2, #8, #13, #24 (resolved/superseded)
- Merge PR #28 (f-string section by @harshitnagar22)
