Architecture diagram links on the deployed landing page returned 404
because the generator emitted 'docs/diagrams/<file>.svg' (repo-relative)
while validate.yml/release.yml deploy the SVGs to '<bundle>/diagrams/'.
Use the same bundle-relative pattern as coverage/cppcheck/traceability
(emit just 'diagrams/<file>.svg').
Also translates two remaining German comments in release.yml
('CI-generierte Artefakte', 'Source-Code zum Anklicken...').
