Drop explicit -u 1000/-g 1000 and let busybox assign from Alpine's
system UID range (100-999), aligning with -S (system account)
semantics. Reference the account by name in USER and --chown to
avoid hard-coding a numeric UID that could collide with future
Alpine releases or layered packages.
* Initial plan
* Update Dockerfile to use golang:1.25 to match go.mod requirement
