The dnephin go-vet hook runs 'go vet' at the repo root, which has no Go files
(all live under cmd/, internal/, pkg/), failing with 'no Go files'. Replace it
with a local 'go vet ./...' hook, mirroring artifactapi.
The initial commit's .gitignore had unanchored 'encapi' and 'encapi-cli'
patterns intended for built binaries; they also matched the cmd/encapi and
cmd/encapi-cli source directories, so those were silently never committed. The
tag build then failed with 'stat /build/cmd/encapi: directory not found'.
- anchor the binary ignores to the repo root (/encapi, /encapi-cli)
- add the cmd/encapi (server) and cmd/encapi-cli (CLI) main packages
