Bump VERSION to 1.0.0 and cut the first tagged release of vpp-maglev. Also in this commit: - maglevc: MAGLEV_SERVER env var as an alternative to the --server flag, matching the MAGLEV_CONFIG / MAGLEV_GRPC_ADDR convention on the other binaries. The flag takes precedence when both are set. - Rename cmd/maglevd -> cmd/server and cmd/maglevc -> cmd/client so the source directory names are decoupled from binary names (the frontend and tester commands already followed this convention). Build outputs and the Debian packages are unchanged.
