feat: 신규 유틸리티 도구 3종 추가 (URL 인코더, URL 디코더, 해시 생성기)

[seonghobae]

본 PR은 사용자의 요구사항을 반영하여 워크스페이스에서 사용할 수 있는 신규 유틸리티 도구 3가지를 자체 기획 및 추가하였습니다.

주요 변경 사항:

1. URL 인코더 (URL Encoder): 입력 텍스트를 URL 퍼센트 인코딩된 포맷으로 변환합니다 (urllib.parse.quote 사용).
2. URL 디코더 (URL Decoder): 퍼센트 인코딩된 URL 문자열을 디코딩하여 일반 텍스트로 복구합니다 (urllib.parse.unquote 사용).
3. 해시 생성기 (Hash Generator): 평문 텍스트를 입력받아 MD5, SHA1, SHA256, SHA512 알고리즘을 사용해 해시 값을 생성합니다 (기본 알고리즘: SHA-256).

테스트 및 검증:

• 추가된 모든 도구에 대한 실패 및 성공 경로 단위 테스트 작성.
• backend/api/tools.py 파일의 테스트 커버리지 100% 달성 및 검증 완료.
• MD5와 SHA1은 usedforsecurity=False 및 # nosemgrep 구문을 통해 보안 스캐너 오탐을 방지했습니다.
• CHANGELOG 작성 및 모든 커밋 내역이 한국어로 이루어졌습니다.

📝 Walkthrough

Walkthrough

The tools API now accepts omitted optional parameters and provides URL encoding, URL decoding, and hash generation for four algorithms. Async API tests cover success, default, and unsupported-algorithm cases.

Changes

Utility tools

Layer / File(s)	Summary
Tool validation and handlers backend/api/tools.py, CHANGELOG.md	Optional parameters are accepted when marked as non-required. URL encoder, URL decoder, and hash generator tools are registered. Hash generation supports MD5, SHA-1, SHA-256, and SHA-512, with SHA-256 as the default.
Endpoint coverage and development support backend/tests/test_tools_api.py, backend/pyproject.toml	Async tests cover URL conversion, all supported hash algorithms, invalid algorithms, and the default algorithm. pytest-cov is added to backend development dependencies.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to b094e

The PR adds three localized utility tools and their tests without any identified correctness, security, availability, or deployment risk; no actionable merge-blocking risk remains beyond normal checks and review.

Current-head review request

Please review the complete current diff at exact head b094ec5b442ffeb7fb117581e8d5af1e985657d8 against base 81c105645ca6e680f5f8c15ba9c33b67eb63c48b.

The Devin finding at backend/api/tools.py:833 was valid: the documented sha256 fallback was unreachable because every schema key was treated as required. The fix adds a narrow optional descriptor recognized by the shared validator and marks only hash_generator.algorithm optional; text remains required. The omitted-algorithm API path now has a regression test.

Verification on this exact source tree:

• PYTHONWARNINGS=error PYTHONPATH=backend python -m pytest backend/tests/test_tools_api.py -q — 72 passed
• ruff check backend/api/tools.py backend/tests/test_tools_api.py — passed
• git diff --check — passed

Please re-evaluate the full changed surface, including the optional-parameter contract, hash algorithm validation, API behavior, dependency changes, and release documentation. Report any finding with exact current-head path and line evidence.

요청하신 부분을 반영하여 hash_generator.algorithm이 누락되더라도 기본값 sha256이 정상 동작하도록 backend/api/tools.py의 _validate_parameters 함수 내에서 required 속성을 처리하도록 수정하였습니다. 회귀 테스트인 test_hash_generator_omitted_algorithm도 성공적으로 통과함을 확인했습니다.

Fixed on current head 212a645d: restored Strix Security Scan to the PR-governance workflow_run dependency so the metadata gate re-evaluates when the asynchronous security result completes. Also made the new pytest-cov dependency exact (7.1.0) and mirrored it in requirements.txt plus hash locks; pytest/release-governance tests passed (107), and Ruff/diff checks are clean.

Repaired at exact head 3aa398dc. The hashed dependency lock now includes the complete coverage==7.15.1 closure required by pytest-cov==7.1.0, generated with uv hashes; utility URL encoder/decoder and hash generator inputs now reuse the existing 100,000-character boundary without altering payload bytes. Added API regressions for oversized input. Validation: PYTHONPATH=. python -m pytest backend/tests/test_tools_api.py -q (75 passed), Ruff clean, git diff --check clean.

Fixed the current-head utility execution issue: the frontend now omits parameters explicitly marked required: false, so hash_generator no longer sends the invalid test_value placeholder for optional algorithm. Added a regression fixture covering the optional descriptor.

Validation: corepack pnpm exec vitest run src/app/tools/page.test.tsx (4 passed); corepack pnpm exec tsc --noEmit; git diff --check. Current head: a6313169e7350da49ffe1c21788fcd68aa5d11aa. Hosted checks are rerunning.
