Add configurable SOURCE_URL footer link; release 0.9.00.9.0

The footer "Site generated ... with <link>" was hardcoded to the shuriken.sh
repository. Make it configurable via the SOURCE_URL config variable and the
--source-url CLI flag (defaulting to the shuriken.sh repo, so existing sites are
unchanged). The footer derives the displayed text from the URL by stripping its
scheme. Plumbed through apply_config_defaults, CLI override targets/spec,
--print-config, the verbose effective-config log, and the header template's
new render_source_url_html (config_html) render var. Documented in
shuriken.default.conf and README; added a generation test asserting a custom
SOURCE_URL replaces the default footer link, and updated the print-config and
header render-var-subset expectations.
