Incorporates the translation content from two external PRs onto current main
(their branches were based on a pre-media-restore history with no common
ancestor, so applied programmatically rather than merged):
- Polish (pl) from #25 (Dawid Matyjasik) — as submitted.
- Korean (ko) from #27 (SeungTaek Lim) — normalized to the dataset convention:
only nested instructions.ko / instruction_steps.ko were kept. The PR's extra
flat top-level *_ko metadata fields (name_ko, target_ko, etc.) were dropped
because they are inconsistent with every other language and would violate
data/exercises.schema.json (additionalProperties: false).
Updates data/exercises.json (all 1,324 records), the embedded EXERCISES blob
and SQL export in index.html, the SQL schemas / INSERT builder / LLM prompt in
setup.html, and README language references (7 -> 9 languages). Change is purely
additive: stripping pl+ko reproduces the previous data byte-for-byte.
