Standard targets:
- build: compiles cmd/librenotes with version/buildtime ldflags
- test: race detector enabled, full module
- lint: go vet, plus staticcheck if available
- run: build + execute, ARGS forwarded
- clean: remove binary and test/coverage artifacts
Variables (BINARY, OUTDIR, GO, GOFLAGS, LDFLAGS, TESTFLAGS) are
overridable so the CI workflow (#5) can invoke targets with
custom output paths or flags.
Closes#38.
