fix(kyberforge): resolve plugin-create path bug, validate.sh false positives, and write-skill YAML error

- plugin-create/SKILL.md: fix ${CLAUDE_PLUGIN_ROOT} path (create-plugin → plugin-create, 4 occurrences)
- plugin-create/SKILL.md: delegate reserved name validation to new references/reserved-names.md (complete list)
- plugin-create/SKILL.md: add displayName reminder in step 4, full-validation pointer in step 7
- plugin-create/references/reserved-names.md: complete reserved name list extracted from claude-code.md
- plugin-create/references/manifest-fields.md: quick-ref for both plugin.json manifests and marketplace entry
- plugin-create/META.md: update stale when: and references: fields to reflect post-migration paths
- plugin-create/assets/plugin-template/hooks.json: unify empty hooks schema to {} (was [])
- write-skill/SKILL.md: fix YAML frontmatter parse error — wrap description in >- block scalar
- validate.sh: strip backtick spans before ../  check to eliminate documentation false positives
- inventory.sh: same backtick-span fix, applied to both outer check and per-line reporting
- tests/test_scripts.sh: fix SCRIPTS_DIR path to skills/marketplace-architect/scripts/
