Walkthrough

Removes Dockerfile’s Go builder stage while keeping a final Alpine stage that still references the missing builder. Cleans comments across multiple Go files without logic changes. Refactors update workflow to compare versions, standardize OS constants, use safer temp-file replacement, and alter Windows update to a manual batch script handoff.

Changes

Cohort / File(s)	Summary
Docker build pipeline Dockerfile	Deleted multi-stage Go builder and related steps; final stage remains and still contains COPY --from=builder ..., creating a mismatch. Simplified user creation and removed comments.
CLI comments cleanup cmd/root.go, internal/cli/manager.go, internal/cli/validation.go, main.go	Removed inline/header comments only; no functional changes. CLI setup, validation, and main flow unchanged.
Update workflow refactor internal/cli/update.go	Added version comparison with early exit if current. Switched OS checks to constants. Reworked download/install to use CreateTemp in exe dir, adjusted perms, and used rename on non-Windows. On Windows, generate batch script with path validation and instruct manual execution; removed os/exec usage.

Poem

A bunny taps the keys—hop, hop, hop!
Trimmed the chatter, let the comments stop.
Updates checked with careful paws,
Temp files snug by filesystem laws.
Docker’s kitchen lost a chef today—
Mind the builder, lest the stew give way. 🥕🐇
