…ovisioning Add snap install path to install.sh so that on Linux systems with snapd available and no native Docker Engine installed, the installer chooses the snap path. Snap is preferred when 'snap' command exists and 'snapd.socket' is active. New functions: - has_snapd(): detects snapd availability via snap command + snapd.socket - has_native_docker(): pre-flight check for conflicting native Docker - install_linux_snap(): installs openshell snap, Docker snap if missing, connects interfaces (best-effort), registers gateway via HTTP, verifies status - register_local_gateway_snap(): gateway add with http:// URL (no mTLS) - wait_for_local_gateway_listener_snap(): waits for HTTP listener linux_package_method() returns 'snap' when snapd is available and no native docker, respecting OPENSHELL_INSTALL_METHOD=classic override. The installer handles the full flow: installing Docker snap if missing, connecting all required interfaces, and registering the gateway.

Fix the snap gateway protocol from https to http to match what the installer actually registers. Correct misleading claims that the installer "exits with an error" and "refuses" snap installs on hosts with native Docker — it silently falls back to classic.

… backend
Add Spread integration tests for install.sh using the image-garden
backend to provision cloud VMs. The test suite covers three install
paths across Ubuntu 24.04/26.04, Debian 13, and Fedora 44:
- install-snap-only: installs OpenShell as a snap on systems with
snapd but no docker
- install-classic: installs OpenShell via native packages (deb/rpm)
on systems with docker (either with or without snapd)
Cloud-init instance templates in .image-garden.mk define the pre-
installed software per system variant. A .gitignore in .image-garden/
excludes generated disk images and VM artifacts.
Tests require image-garden snap, version 0.6 from the --candidate
channel.

…e-garden backend" This reverts commit d907412. For now, do not add spread. We will consider adding it in the future as a means to test openshell on a matrix of Linux systems. Signed-off-by: Oliver Calder <oliver.calder@canonical.com>
Adjust the wording of the installation docs for the `openshell` snap. In particular, clarify when the snap will be installed, how it currently requires the docker snap, and how to override the installation method. Also, prune some of the manual interface connections, as these have since been granted autoconnection via snap store assertions.

As @drew suggested, add `deb`, `rpm`, `snap`, and `homebrew` as installation methods which the user can specify via `OPENSHELL_INSTALL_METHOD` rather than falling back to detecting the package manager automatically. `homebrew` is not yet supported on Linux, and it is the only supported option on MacOS. Also adds a TODO to implement `install_linux_homebrew` in the future. Signed-off-by: Oliver Calder <oliver.calder@canonical.com>
