docs: clean up CHANGELOG.md — remove 40 duplicate section blocks and RU mirror (#122)

* chore: add workspace clippy lints, release profiles, COMPAT.md, diff-registry.sh

- Workspace clippy lints: or_fun_call, redundant_clone, collection_is_never_read,
  naive_bytecount, stable_sort_primitive, large_types_passed_by_value, assigning_clones
- Fix or_fun_call in cargo_registry.rs (unwrap_or -> unwrap_or_else)
- Release profiles: release (thin LTO) + release-official (full LTO, codegen-units=1)
- COMPAT.md: protocol compatibility matrix for all 7 registries (40 endpoints)
- scripts/diff-registry.sh: differential smoke tests (Docker/npm/Cargo/PyPI/Go/Raw)

* ci: add typos spell-check job and config

* chore: add .git-blame-ignore-revs for bulk fmt/clippy commits

* chore: unify PR template with What/Why/Checklist format

* docs: add new registry checklist and improve contributing guide

* fix: correct typos action SHA to v1.45.0

 # Changelog
+## [Unreleased]
+
+## [0.5.0] - 2026-04-07
+
+### Added
+- **Cargo sparse index (RFC 2789)** — cargo can now use NORA as a proper registry with `sparse+http://` protocol, including `config.json`, prefix-based index lookup, and `cargo publish` wire format support
+- **Cargo publish** — full publish flow with wire format parsing, version immutability (409 Conflict), SHA-256 checksums in sparse index, and proper `warnings` response format
+- **PyPI twine upload** — `twine upload` via multipart/form-data with SHA-256 verification, filename validation, and version immutability
+- **PEP 691 JSON API** — content negotiation via `Accept: application/vnd.pypi.simple.v1+json` for package index and version listing, with hash digests in responses
+- 577 total tests (up from 504), including 25 new Cargo tests and 18 new PyPI tests
+
+### Fixed
+- Go and Raw registries missing from Prometheus metrics (`detect_registry` labeled both as "other") (PR #97, @TickTockBent)
+- Go and Raw registries missing from `/health` endpoint `registries` object (PR #97, @TickTockBent)
+- Garbage collection scoped to Docker-only blobs — prevents GC from deleting non-Docker registry data (PR #109, @TickTockBent)
+- Correct `zeroize` annotation placement and avoid secret cloning in `protected.rs` (PR #108, @TickTockBent)
+- Cargo dependency field mapping: `version_req` correctly renamed to `req` and `explicit_name_in_toml` to `package` in sparse index entries, matching Cargo registry specification
+- Cargo crate names normalized to lowercase across all endpoints (publish, download, metadata, sparse index) for consistent storage keys
+- Cargo publish write ordering: index written before .crate tarball to prevent orphaned files on partial failure
+- Cargo conflict errors now return Cargo-compatible JSON format (`{"errors": [{"detail": "..."}]}`)
+- PyPI hash fragments preserved when rewriting upstream links (PEP 503 compliance)
+- Redundant path traversal checks removed from crate name validation (charset already excludes unsafe characters)
+
+### Changed
+- Cargo sparse index and config.json responses include `Cache-Control: public, max-age=300`
+- Cargo .crate downloads include `Cache-Control: public, max-age=31536000, immutable` and `Content-Type: application/x-tar`
+- axum upgraded with `multipart` feature for PyPI upload support

-### Добавлено

-#### UI: SVG иконки брендов
-- Эмоджи заменены на SVG иконки брендов (стиль Simple Icons)
-- Docker, Maven, npm, Cargo, PyPI теперь отображаются как векторная графика
-- Единый стиль иконок на дашборде, сайдбаре и страницах деталей
-
-#### Тестовая инфраструктура
-- Unit-тесты для LocalStorage (8 тестов): put/get, list, stat, health_check
-- Unit-тесты для S3Storage с HTTP-мокированием wiremock (11 тестов)
-- Интеграционные тесты auth/htpasswd (7 тестов)
-- Тесты жизненного цикла токенов (11 тестов)
-- Тесты валидации (21 тест)
-- **Всего: 75 тестов проходят**
-
-#### Безопасность: Валидация ввода (`validation.rs`)
-- Защита от path traversal: отклоняет `../`, `..\\`, null-байты, абсолютные пути
-- Валидация имён Docker-образов по спецификации OCI distribution
-- Валидация дайджестов (`sha256:[64 hex]`, `sha512:[128 hex]`)
-- Валидация тегов и ссылок Docker
-- Ограничение длины ключей хранилища (макс. 1024 символа)
-
-#### Безопасность: Rate Limiting (`rate_limit.rs`)
-- Auth endpoints: 1 req/sec, burst 5 (защита от брутфорса)
-- Upload endpoints: 10 req/sec, burst 20
-- Общие endpoints: 100 req/sec, burst 200
-- Использует `tower_governor` 0.8 с `PeerIpKeyExtractor`
-
-#### Наблюдаемость: Отслеживание Request ID (`request_id.rs`)
-- Заголовок `X-Request-ID` добавляется ко всем ответам
-- Принимает upstream request ID или генерирует UUID v4
-- Tracing spans включают request_id для корреляции логов
-
-#### CLI: Команда миграции (`migrate.rs`)
-- `nora migrate --from local --to s3` - миграция между storage backends
-- Флаг `--dry-run` для предпросмотра без копирования
-- Прогресс-бар с indicatif
-- Пропуск существующих файлов в destination
-- Итоговая статистика (migrated, skipped, failed, bytes)
-
-#### Обработка ошибок (`error.rs`)
-- Enum `AppError` с `IntoResponse` для Axum
-- Автоматическая конверсия из `StorageError` и `ValidationError`
-- JSON-ответы об ошибках с поддержкой request_id
-
-### Изменено
-- `StorageError` теперь использует макрос `thiserror`
-- `TokenError` теперь использует макрос `thiserror`
-- Storage wrapper валидирует ключи перед делегированием backend
-- Docker registry handlers валидируют name, digest, reference
-- Лимит размера body установлен в 100MB через `DefaultBodyLimit`
-
-### Добавлены зависимости
-- `thiserror = "2"` - типизированная обработка ошибок
-- `tower_governor = "0.8"` - rate limiting
-- `governor = "0.10"` - backend для rate limiting
-- `tempfile = "3"` (dev) - временные директории для тестов
-- `wiremock = "0.6"` (dev) - HTTP-мокирование для S3 тестов
-
-### Добавлены файлы
-- `src/validation.rs` - модуль валидации ввода
-- `src/migrate.rs` - модуль миграции хранилища
-- `src/error.rs` - типы ошибок приложения
-- `src/request_id.rs` - middleware для request ID
-- `src/rate_limit.rs` - конфигурация rate limiting
