rename: video-orchestrator → kanban-video-orchestrator

The kanban prefix makes the skill discoverable alongside `kanban-orchestrator`
and `kanban-worker`, and signals up front that this skill drives the kanban
plugin rather than being a generic video tool.

Updated:
- directory rename
- SKILL.md frontmatter `name:` and H1
- setup.sh.tmpl header

optional-skills/creative/kanban-video-orchestrator/assets/brief.md.tmpl
