Basicrum community installer v0.0.6

Installer built from commit b71508a0b6bc9b9d14a3c7efc341ad90f0a27f95.

Install or update with the same command:

curl -fsSL https://github.com/basicrum/basicrum-single-instance-community/releases/latest/download/install.sh | bash

The first run now prints one requirements summary: what is ready, what needs action, and what can only be checked after Docker is installed or started. It checks the Docker CLI, Engine, Compose plugin, host tools, CPU, RAM, and storage independently where possible, then stops before changing the installation if anything required is missing. This installer still bundles application image tag 0.0.1.

Validated with 40 installer tests and a fresh Linux Docker installation followed by a rerun. All six services passed healthchecks and the login endpoint returned HTTP 200. Download install.sh and install.sh.sha256 to verify with sha256sum --check install.sh.sha256.
