create and switch to a non-root user in the runtime stage: add a system
user/group (e.g., "app" or "nitewatch"), ensure ownership of the copied binary
(/usr/local/bin/nitewatch) and any runtime dirs are chowned to that user, and
set USER to that non-root account so the nitewatch process from the builder
stage no longer runs as root.

Run the final image as a non-root user.
The runtime stage never sets USER, so nitewatch runs as root. For a network-facing process, that is unnecessary privilege if the process is compromised.

1. builder stage (golang:1.25-alpine) — installs build-base, downloads dependencies, and compiles the binary. 2. Runtime stage (alpine:3.21) — a minimal image with only ca-certificates and the compiled binary. No Go toolchain, no build tools. This will produce a significantly smaller final image since the Go SDK, source code, and build dependencies are all left behind in the builder stage.

- Line 1: The PR description and the Dockerfile disagree on the Go base image;
the Dockerfile uses the Dockerfile line "FROM golang:1.24-alpine" while the PR
text mentions "golang:1.25-alpine". Update the PR description to state the exact
intended Go version (e.g., 1.24 or 1.25) to match the Dockerfile, or if you
intended to change the Dockerfile instead, update the Dockerfile's FROM line
accordingly and note that change in the PR description so both sources are

Clarify Go version choice in PR description.
The Dockerfile specifies golang:1.24-alpine, but the PR description mentions golang:1.25-alpine. Both tags exist and are valid. Please update the PR description to match the intended version or clarify if this is an intentional downgrade.
