chore: upgrade js-yaml 3.x → 4.x and csv-parser 2.x → 3.x in csv-to-pg

[pyramation]

Summary

Bumps two major dependencies in the csv-to-pg package:

Package	From	To	Breaking changes
js-yaml	^3.14.0 (resolved 3.14.2)	^4.1.0 (resolved 4.1.1)	safeLoad() → load(), unsafe types removed from default schema
csv-parser	^2.3.3 (resolved 2.3.5)	^3.2.0 (resolved 3.2.0)	Minimum Node bumped to 10; streaming API unchanged

No source code changes were needed. The codebase already uses import { load as parseYAML } from 'js-yaml' (the v4 API name), and csv-parser is used via the standard createReadStream().pipe(csv(opts)) streaming pattern which is unchanged in v3.

The csv-parser upgrade also cleans up transitive deps — it no longer pulls in minimist or through2@3.0.2.

Review & Testing Checklist for Human

• js-yaml behavior change: In v3, load() was the unsafe variant (allowed !!js/function, !!js/regexp, etc). In v4, load() is the safe variant (equivalent to old safeLoad()). If any YAML config files consumed by csv-to-pg's readConfig() use custom JS types, they will now throw. Verify your YAML configs only use standard YAML types.
• Lockfile @types/node drift: The lockfile shows several transitive resolutions shifting from @types/node@22.19.11 to @types/node@25.3.3 (in ts-node, grafserv, postgraphile resolution strings). This appears to be a pnpm lockfile artifact from regeneration, not an intentional change. Verify these don't introduce unwanted Node 25 types into packages that should target Node 22.
• Run csv-to-pg tests: cd packages/csv-to-pg && pnpm test — CI will cover this, but worth a manual check since both upgrades are major versions with no source code changes to validate compatibility.

Notes

• Build passed locally with pnpm build
• CI not yet verified — waiting for checks to complete
• The csv-parser v3 upgrade has been in production for many projects (it's a mature package), and the streaming API is backward-compatible
