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.

Resolved README.md conflict with #34: kept both the instructions.hi row and
the instruction_steps.<lang> row (extended to include hi).

Adds data/exercises.schema.json (Draft 2020-12) describing every field,
its type and constraints, so the dataset and community additions can be
validated with any standard JSON Schema validator. Validated against all
1,324 records with zero errors.
Also documents the previously undocumented instruction_steps field and
references the schema from the README.
