Move beszel_agent_data, beszel_data, and beszel_socket directories
into development/ alongside beszel.docker-compose.yml. Add .gitignore
for volatile data (dbs, sockets) while keeping the fingerprint.
Recovered all beszel integration files from the local worktree
at /Users/ajnart/.cursor/worktrees/homarr/pwxp that were built
and tested with the homarr:beszel docker image.
