registry: remove tools with zero users

[jdx]

Summary

• Removes 49 registry entries with zero recorded users
• Users can still install any of these via explicit backend syntax (e.g. mise use aqua:cloudfoundry/uaa-cli, mise use github:exaloop/codon) — only the registry shorthand is being dropped
• Skipped 6 tools added in 2026 (mysql-client, dependency-check, neo4j, codon, wasm-tools, code-review-graph) — too new to judge by user count

Removed tools

bosh-backup-and-restore (bbr), brig, btrace, carp, clarinet, cli53, concourse, conduit, copper, credhub, datree, djinni, dome, draft, dtm, envcli, esy, glen, grain, inlets, kcctl, ki, kpack (kp), krab, kube-credential-cache, kubefedctl, kubefirst, kubemqctl, kwt, lab, lane, levant, melt, opsgenie-lamp, pachctl, psc-package, purerl, redo, rke, sinker, soracom, starboard, sver, terradozer, titan, uaa (uaa-cli), wasm4, wren (wren-cli), zbctl

Test plan

• CI build passes (registry is generated from registry/ at build time, so removing files just drops them from the generated map)

Note

Medium Risk
Moderate risk because it changes CI gating/conditions for test-tool, which could accidentally skip registry validation if the diff detection is wrong. Functional impact is limited to workflow behavior and removal of registry entries.

Overview
Removes 49 registry/*.toml entries, dropping their shorthand names from the registry.

Updates the registry CI diff logic to treat only added/modified registry files as test candidates and introduces a skip-test-tool flag so deletion-only PRs skip test-tool and still pass the aggregate registry-ci gate cleanly.

Code Review

This pull request removes a large collection of tool configuration files for various utilities such as BOSH Backup and Restore, Brigade, BTrace, Carp, and several Kubernetes-related tools. I have no feedback to provide.

Greptile Summary

This PR removes 49 registry shorthand entries for tools with zero recorded users, keeping them accessible via explicit backend syntax. It also updates the CI pipeline to handle deletion-only PRs gracefully by skipping the test-tool job when no registry files were added or modified.

• Registry deletions: 49 registry/*.toml files are dropped; users can still install these tools via aqua:, github:, etc. explicit refs.
• registry-diff action: adds --diff-filter=AM so deleted files are excluded from the list of tools to test.
• registry.yml workflow: introduces a skip-test-tool output and short-circuits the test-tool job (and the final-check gate) when the diff contains only deletions.

Confidence Score: 5/5

Safe to merge — all changes are either file deletions or CI guard-rail additions with no risk to production behaviour.

The registry deletions are mechanical and reversible; users who depended on the shorthand can switch to the explicit backend syntax. The workflow changes correctly gate test-tool on the presence of added/modified files and handle the skipped state in final-check, so CI remains green for deletion-only PRs without weakening any required checks.

No files require special attention.

Important Files Changed

Filename	Overview
.github/actions/registry-diff/action.yml	Added --diff-filter=AM to exclude deleted registry files from the modified_tools list; correct and targeted fix.
.github/workflows/registry.yml	Adds skip-test-tool output and short-circuits test-tool job for deletion-only PRs; final-check gate also updated to accept the skipped state.
