2026-08-06Add skiff config set/unset/list, backed by /app/env in the app's datasetClaude
Config vars are plain env vars, injected into both the running app (via rc.d) and the release phase, and versioned on the same ZFS snapshot timeline as deploys - a bad config change gets the same automatic snapshot/restart/health-check/rollback guarantee a bad deploy already gets. Extracts deploy.go's health check into internal/health so both paths share it. Verified end-to-end against a FreeBSD VM: config set/unset, automatic rollback on a health-check failure, and explicit `skiff rollback` all correctly carry the env file along with the rest of the dataset.
2026-08-05Simplify: centralize paths in layout, dedup zfs snapshot refs, remove dead codeClaude
- Add layout.Config methods (ReleasesDir, PostReceiveHookPath, RCScriptPath, RCConfPath) so main.go and jailmgr no longer hand-build paths that layout already owns. - Extract zfsutil.snapRef to replace three inline dataset@tag Sprintfs. - Remove seven unused exported functions (zfsutil.Exists, jailmgr.Stop, sh.RunWithStdinFile, and four dead layout.Config path methods) and their now-unused imports.
