fix(data-deploy): add csv gem for Ruby 3.4 jekyll build#53
Merged
Conversation
Ruby 3.4 dropped csv from the default gems. The data-deploy workflow was bumped to Ruby 3.4 (a6c0730), so `bundle exec jekyll build` now fails with `cannot load such file -- csv (LoadError)` across all relaton-data-* repos. Declare csv explicitly in the Gemfile.deploy template so it is part of the bundle. Propagates to every data repo via Cimas. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Ruby 3.4 dropped csv from the default gems. The data-deploy workflow runs on Ruby 3.4, so `bundle exec jekyll build` fails with `cannot load such file -- csv (LoadError)`. Mirrors the upstream Cimas template fix (relaton/support#53); the next Cimas sync regenerates Gemfile.deploy with identical content. Also ignore .claude/settings.local.json.

Problem
The scheduled Deploy workflow fails at the Jekyll build step across
relaton-data-*repos:```
jekyll-4.3.4/lib/jekyll.rb:28: csv was loaded from the standard library,
but is not part of the default gems starting from Ruby 3.4.0.
cannot load such file -- csv (LoadError)
```
Ruby 3.4 dropped `csv` from the default gems (now only a bundled gem). The data-deploy workflow was bumped to Ruby 3.4 in a6c0730, so `bundle exec jekyll build` can no longer load `csv` unless it is declared in the bundle.
Example failure: https://github.com/relaton/relaton-data-w3c/actions/runs/27504966889/job/81294417350
Fix
Declare `csv` explicitly in the `Gemfile.deploy` Cimas template. This propagates to every data repo (~27) on the next Cimas sync, fixing all of them at once.
