feat: add cspell configuration and CI spell-check (#87)

* feat: add cspell configuration and CI spell-check

- Add cspell.json with Deepnote-specific file patterns
- Configure spell-check to only check Deepnote code (not forked Microsoft code)
- Add minimal 35-word technical dictionary
- Add spell-check CI job to GitHub Actions workflow
- Update package.json scripts to use cspell config

Result: 49 files checked (Deepnote-specific only), 0 spelling errors

* fix: format cspell.json and exclude cspell dictionary from license check

* refactor: simplify spell-check scripts

- Remove spell-check:fix script (didn't actually fix, just showed suggestions)
- Add explicit --config cspell.json to spell-check script for clarity
