docs(reports): Korean report 1059 is missing section 3.2 from the English original

## Summary

The Korean translation of technical report 1059 is missing a whole section that the English original has. It is the only en/ko heading-count mismatch in the entire `TECHNICAL_REPORTS/` directory.

## Background

The English report carries `### 3.2 Invert the variable or rename it`, a short "not applicable, recorded because PR #1062 went the other way" note between section 3.1 and section 4. The Korean version jumps straight from `### 3.1` to `## 4. 구현 상세`, dropping 3.2. Comparing headings across all report pairs in the directory, this is the only mismatch, so the fix is bounded.

## Proposed Solution

Translate the short 3.2 section into Korean and insert it after 3.1, imitating the surrounding Korean style already in the file.

## Implementation Notes

- English: `TECHNICAL_REPORTS/1059-cuda-jit-dtype-key-sweep-20260807.en.md:95` has `### 3.2 Invert the variable or rename it`.
- Korean: `TECHNICAL_REPORTS/1059-cuda-jit-dtype-key-sweep-20260807.ko.md` goes from `### 3.1` (line 80) directly to `## 4. 구현 상세` (line 97).
- A heading-by-heading comparison confirms every other section matches, so only 3.2 needs to be added.

## Acceptance Criteria

- [ ] The ko report carries section 3.2 with content equivalent to the English original

## Original Suggestion

### Title: docs(reports): Korean report 1059 is missing section 3.2 from the English original

The Korean translation of technical report 1059 is missing a whole section that the English original has — the only en/ko heading-count mismatch in the entire `TECHNICAL_REPORTS/` directory.

## Evidence

- `TECHNICAL_REPORTS/1059-cuda-jit-dtype-key-sweep-20260807.en.md:95-99` — `### 3.2 Invert the variable or rename it` (a short "not applicable, recorded because PR #1062 went the other way" note)
- `TECHNICAL_REPORTS/1059-cuda-jit-dtype-key-sweep-20260807.ko.md` — jumps from `### 3.1` (line 80) straight to `## 4. 구현 상세` (line 97)
- Verified across all report pairs in the directory (ignoring code fences): this is the only heading-count mismatch, so the fix is bounded

## Suggested fix

Translate the short 3.2 section into Korean and insert it after 3.1; the surrounding Korean style is right there to imitate.

## Acceptance criteria

- [ ] The ko report carries section 3.2 with content equivalent to the English original

Read section 3.2 at TECHNICAL_REPORTS/1059-cuda-jit-dtype-key-sweep-20260807.en.md:95-99, then inspect the Korean file around section 3.1 and section 4. Translate the short missing note into Korean and insert it after 3.1. Done means the Korean report contains section 3.2 with content equivalent to the English original.
