Bring the repo into conformance with the scripts-to-rule-them-all
(STRTA) scaffold. The real logic that lived inline in the Makefile now
lives in POSIX-sh entrypoints under script/, and the Makefile's standard
targets are thin @script/NAME shims.
- script/: bootstrap, setup, projectname, test, lint, fmt, fmt-check,
check, docker, precommit, install-precommit, cibuild. All are
executable #!/bin/sh entrypoints; the go mod tidy guard from the old
inline hooks recipe moved into script/precommit.
- Makefile: the nine standard targets (bootstrap, setup, test, lint,
fmt, fmt-check, check, docker, hooks) are now thin shims; the
repo-specific sfdupes/build/clean targets and the CGO_ENABLED export
are preserved.
- .gitea/workflows/check.yml: run script/cibuild instead of a bare
docker build.
- Dockerfile: run make check (and the build) as an unprivileged builder
user rather than root. We should never build or run as root, and doing
so also lets the permission-denied tests run legitimately: root
bypasses the chmod(0) that TestScanHardlinkRunFailsTogether relies on,
which made the in-image make check fail. HOME and the Go caches point
at the user's home so go build/test and golangci-lint can write.
make check passes locally and docker build . is green (the in-image
non-root make check passes, including the hardlink permission test).
