fix(kyberforge): co-locate evals/tests with skills and fix manifest inconsistencies

Move all evals into each skill's own evals/ directory and test_scripts.sh into
marketplace-architect/scripts/ so test artefacts live alongside the code they test.
Also fix: hooks.json array→object, displayName title-case, marketplace.json owner
placeholders, and .github/plugin/marketplace.json metadata-wrapper schema divergence.
