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/

+# Reserved Plugin and Marketplace Names
+
+These names are blocked for third-party use by the Claude Code marketplace. Reject any
+plugin or marketplace name that matches an exact entry or a wildcard pattern below.
+
+## Exact reserved names
+
+```
+claude-code-marketplace
+claude-code-plugins
+claude-plugins-official
+claude-plugins-community
+claude-community
+anthropic-marketplace
+anthropic-plugins
+agent-skills
+anthropic-agent-skills
+knowledge-work-plugins
+life-sciences
+claude-for-legal
+claude-for-financial-services
+financial-services-plugins
+```
+
+## Reserved name patterns (prefix match)
+
+Any name starting with these strings is reserved:
+
+```
+anthropic-
+claude-
+official-claude
+anthropic-tools
+```
+
+## Kebab-case requirement
+
+Plugin names must match `^[a-z0-9]+(-[a-z0-9]+)*$` — lowercase letters, digits, and
+hyphens only. No underscores, spaces, or uppercase. The Claude.ai marketplace sync rejects
+non-kebab-case names even if the local CLI tolerates them.
+
+## How to check
+
+1. Exact match: is the name in the exact reserved list above?
+2. Pattern match: does the name start with any reserved prefix?
+3. Format: does the name match the kebab-case regex?
+
+If any check fails, halt and ask the user for a different name before continuing.
