build(debian): add a Debian and Ubuntu package definition

Add a debhelper-free debian/ tree so a .deb can be built with the Go toolchain and dpkg-dev alone. debian/rules compiles the binary with -trimpath and the version from debian/changelog, then stages the binary, the lazyntfy(1) man page, the license, and the README. The package Depends on ca-certificates for TLS to the ntfy server.

+Description: lazygit-style terminal client for ntfy
+ lazyntfy is a terminal user interface for the ntfy pub-sub notification
+ service, laid out like lazygit: topics in the left pane, messages in the
+ middle pane, and the selected message in the right pane.
+ .
+ It speaks the ntfy HTTP API directly, subscribes to several topics over a
+ single stream, reconnects automatically, summarizes Grafana and Alertmanager
+ webhook bodies, and remembers topics and messages between runs in a small
+ SQLite database.
