Summary

Preserve nonblank build/start/pre-deploy/cron command bytes, and keep explicit blank root/health/pre-deploy overrides long enough to clear clone defaults. Omitted settings retain their existing inheritance behavior.

Motivation

Trimming an escaped trailing space changes the command's argument; normalizing an explicit blank to nil can instead inherit a source setting the caller removed. Both occur at the shared service-input normalization boundary.

How to verify

go test ./cmd/... ./pkg/... ./internal/...

• All 57 development packages pass on the candidate.
• Normalizer and real create/update command tests inspect the fake API request bodies for exact command bytes, nil/blank behavior and clone clears across service types. A fresh command factory and a shared fake-create endpoint isolate the command tests.
• New-code lint is clean against c31e586e; full lint on unmodified main reports 92 pre-existing findings with the pinned golangci-lint v2.14.0.

Release notes

Service commands preserve nonblank executable text, and clones honor explicit blank optional overrides.
