Summary

Move SDK releases from Cloudsmith to the PlotJuggler JFrog Artifactory Conan repository — the remote pj-official-plugins already resolves and primes (PlotJuggler/pj-official-plugins#278), so a released SDK binary lands exactly where consumers look for it instead of being rebuilt from source there.

• Remote: https://plotjuggler.jfrog.io/artifactory/api/conan/plotjuggler-conan, defined once as a workflow env. Uploads use the org-level JFROG_USER/JFROG_TOKEN (already visible to this repo — no new secrets). The re-publish guard reads anonymously (anonymous read is enabled on the repository).
• Guard fix: Artifactory reports an unpublished version as "error": "404: Not Found", not RECIPEUNKNOWN; without this the first release of every version would have fallen into the "proceeding without the guard" branch.
• Matrix aligned with consumers: ubuntu-22.04, ubuntu-22.04-arm, macos-14, windows-2022, windows-11-arm — the images pj-official-plugins CI/release use, so the published package_ids (gcc 11 / apple-clang 15 arm64 / msvc 194) match what downstream conan install computes. Replaces macos-15-intel (Intel macOS not a supported target) and windows-latest; adds Linux aarch64 and Windows arm64.
• Release-notes snippet and packaging/conan-center-index/README.md now point at the JFrog remote. No Cloudsmith reference remains in the repo.

Verification

• Anonymous conan list "plotjuggler_sdk/*" -r plotjuggler-conan works from a clean CONAN_HOME; 0.25.0 (unpublished) returns the 404: Not Found JSON the guard now handles, 0.24.0 returns its revision.
• The five runners can build the SDK: pj-official-plugins' 2026-08-31 release run compiled plotjuggler_sdk from source on every one of them.
• YAML parsed; pre-commit green. The workflow itself only runs on a v* tag — first real exercise will be the next SDK release (v0.25.0 is current VERSION, not yet published on JFrog).

Follow-ups

• CLOUDSMITH_USER / CLOUDSMITH_API_KEY repo secrets become unused after merge and can be deleted.
• linux-ci.yml / macos-ci.yml / windows-ci.yml still run on macos-15-intel / windows-latest; aligning CI runners with the release matrix is a separate change.

Second commit (from an independent Codex review of the diff):

• workflow_dispatch re-runs derived the version from GITHUB_REF_NAME (= main on a manual run), so every retry / allow_republish run failed the VERSION check — now derived from the tag input, passed via env.
• The re-publish guard now fails closed on any remote error other than the recognised "not found" (previously it warned and published without the guard).

Runner-image notes, no change made (producer and consumer share the labels, so they migrate together):

• windows-11-arm moves to VS 2026 (msvc 195) during 21–30 Sept 2026 (runner-images#14602) — SDK versions released before then will fall back to source on that leg until re-released.
• macos-14 retires 2 Nov 2026 (runner-images#13518) — both repos will need a coordinated move (e.g. macos-15, apple-clang 17, whose binaries JFrog already partially holds).
