report and trees take optional PATH operands and use only the records
at or below them. Operands are made absolute and cleaned as text, never
looked up on the filesystem. With operands, trees reports only
directories at or below an operand: a directory above them holds
unused files, so its digest neither gets reported nor suppresses its
children's group. The summary still counts every record read.
Model: opus-5-5
`go install sneak.berlin/go/sfdupes/cmd/sfdupes@...` found no package: the command was built from `package main` in the repository root. It now lives in `cmd/sfdupes/main.go`, whose one call is `sfdupes.Main()`, and every other Go file moved with `git mv` to `internal/sfdupes`, as `REPO_POLICIES.md` and the Go style guide require. The `Makefile` builds `./cmd/sfdupes` and sets `Version` by its new import path. README "Install" and `TODO.md` give the new paths; the fleet-written "flat layout" divergence is gone.
Rule suppressed: each test file carries `//nolint:testpackage`, since the tests call unexported functions throughout.
