Add ai-team-orchestration plugin: multi-agent dev team with Producer, Dev Team, QA agents (#1504)

* Add ai-team-orchestration plugin: multi-agent dev team with Producer, Dev Team, QA agents

* fix: use kebab-case agent names to match filenames

* fix: regenerate README after agent name change

* fix: address Copilot review — add edit tools to Producer/QA, use GitHub closing keywords

* fix: update agent tools to official VS Code tool set names

Replace outdated/nonexistent tool names with current official tool sets:
- Producer: search, read, edit, web (removed nonexistent githubRepo)
- Dev Team: search, read, edit, execute, web (replaced runCommands, problems, usages, etc.)
- QA: search, read, edit, execute, web (removed nonexistent findTestFiles, runTests)

* fix: remove frontmatter from plugin README per reviewer feedback
