fix: audit and repair all plugins, agents, and commands
- Fix 12 command files: correct CLI arg syntax, script paths, and usage docs
- Fix 3 agents with broken script/reference paths (cs-content-creator,
cs-demand-gen-specialist, cs-financial-analyst)
- Add complete YAML frontmatter to 5 agents (cs-growth-strategist,
cs-engineering-lead, cs-senior-engineer, cs-financial-analyst,
cs-quality-regulatory)
- Fix cs-ceo-advisor related agent path
- Update marketplace.json metadata counts (224 tools, 341 refs, 14 agents,
12 commands)
Verified: all 19 scripts pass --help, all 14 agent paths resolve, mkdocs
builds clean.
