fix(debian): avoid restarting treeland on upgrade

[wineee]

treeland.service is managed by DDM at runtime, but the package installs it as a systemd system unit. With the default dh_installsystemd behavior, debhelper generates maintainer script snippets that can start or restart the unit during package install and upgrade. That makes upgrading the treeland package disrupt the active compositor/greeter session.

Override dh_installsystemd with --no-start and --no-stop-on-upgrade so package operations do not change the running treeland.service state. DDM remains responsible for explicitly starting and stopping the compositor.

Also add the missing ${misc:Depends} substitutions and normalize the treeland-dev dependency formatting so debhelper-generated dependencies are preserved in the binary package metadata.

Adjusts Debian packaging so treeland.service is not automatically started or restarted during install/upgrade, and cleans up debhelper-related dependencies and formatting in debian/control.

File-Level Changes

Change	Details	Files
Prevent dpkg/debhelper from starting or restarting treeland.service during install and upgrade so DDM remains the sole runtime controller.	Override the default dh_installsystemd behavior in debian/rules to pass --no-start so the unit is not auto-started on install Add --no-stop-on-upgrade to the dh_installsystemd invocation so upgrades do not stop/restart the running treeland.service Ensure the service remains installed as a systemd unit but its lifecycle is managed exclusively by DDM	debian/rules
Fix debhelper substitution dependencies and normalize package dependency formatting for treeland-dev.	Add the missing ${misc:Depends} substitution so debhelper-generated misc dependencies are kept in the binary package metadata Normalize the Depends field formatting for treeland-dev to the preferred multi-line or canonical style without changing semantics, ensuring compatibility with debhelper Perform minor control file cleanup consistent with Debian policy and packaging practices	debian/control
