…5715) DHI advisories publish release-lineage PURLs — `pkg:apk/dhi/<name>` (Alpine lineage) and `pkg:deb/dhi/<name>` (Debian lineage) — but the reverse PURL map only knew `pkg:dhi/<name>`, so PURL-form `/v1/query` requests never resolved to the `Docker Hardened Images` ecosystem. This adds `(apk, dhi)` and `(deb, dhi)` to the reverse lookup map. The `dhi` namespace disambiguates from Alpine `(apk, alpine)` and Debian `(deb, debian)`, so there is no collision. Forward generation (`package_to_purl`) is intentionally left as `pkg:dhi/…`: it receives the ecosystem name after `ecosystems.normalize()` has stripped the `:Alpine:`/`:Debian:` lineage, so it cannot choose apk vs deb — and DHI feed records always ship their own PURL, so that path is not exercised for DHI in practice. Tests added in `osv/purl_helpers_test.py`. Relates to #4388. 🤖 Generated with [Claude Code](https://claude.com/claude-code)

… Images (#5716) `Docker Hardened Images` was registered as a `SemverEcosystem`, but DHI OS packages are repackaged Alpine (apk) and Debian (dpkg) packages that keep their upstream version syntax (e.g. `8.4.0-r0`, `7.88.1-10+deb13u2`). Semver comparison mis-orders these — it compares the apk `-rN` release lexically (so `r10` sorts before `r2`) and does not understand Debian epochs/revisions. This adds a `DHIEcosystem` helper that delegates version handling to the lineage ecosystem named in the `<lineage>:<release>` suffix — Alpine/APK for `…:Alpine:<rel>`, Debian for `…:Debian:<rel>` — mirroring the existing `TuxCareEcosystem` wrap-an-inner pattern. As a result `Docker Hardened Images` is no longer reported as semver. Tests added in `osv/ecosystems/_ecosystems_test.py`. Relates to #4388. 🤖 Generated with [Claude Code](https://claude.com/claude-code)
