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)

 # 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
+
+
+## [0.4.0] - 2026-04-05

+- **--json output for mirror** — nora mirror npm --json outputs structured JSON for CI/CD pipelines (#43)

+- Env var naming unified across all registries (#39, #90)
+
+## [0.3.1] - 2026-04-05

-# Roadmap
-
-> This roadmap reflects current priorities. It may change based on community feedback.
-
-## Recently Completed
-
-- **v0.2.32** — Docker dashboard fix for namespaced images, `library/` auto-prepend for Hub official images
-- **v0.2.31** — npm full proxy (URL rewriting, scoped packages, publish, SHA-256 integrity cache, metadata TTL)
-- **v0.2.29** — Upstream authentication for all protocols (Docker, Maven, npm, PyPI)
-
-## In Progress
-
-- **`nora mirror`** — Pre-fetch dependencies from lockfiles for air-gapped environments ([#40](https://github.com/getnora-io/nora/issues/40))
-  - npm: `package-lock.json` (v1/v2/v3)
-  - pip: `requirements.txt`
-  - cargo: `Cargo.lock`
-  - maven: dependency list
-
-## Next Up
-
-- **Consistent env var naming** — Unify `NORA_*_PROXY` / `NORA_*_UPSTREAMS` across all protocols ([#39](https://github.com/getnora-io/nora/issues/39))
-- **Package blocklist** — Deny specific packages or versions via config ([#41](https://github.com/getnora-io/nora/issues/41))
-- **Multiple upstreams for npm/PyPI** — Same as Maven already supports
-- **v1.0.0 release** — Stable API, production-ready
-
-## Future
-
-- Docker image mirroring ([#42](https://github.com/getnora-io/nora/issues/42))
-- Virtual repositories via config (named endpoints with custom search order)
-- Path-based ACL (per-namespace write permissions)
-- OIDC/LDAP authentication
-- HA mode (stateless API + external database)
-- Golang modules proxy
-- Content trust (Cosign/Notation verification)
-
-## How to Influence
-
-Open an issue or join [Telegram](https://t.me/getnora) to discuss priorities.
