feat: create team-based multi-repo sync and CI fix plugin

[JacobPEvans]

Parent

Part of #14 (epic: migrate workaround orchestration patterns to native Claude Agent Teams)

Summary

Create a team-repo-ops plugin that uses Agent Teams to coordinate work across multiple repositories simultaneously - syncing branches, fixing CI failures, and managing PRs in parallel.

Problem

Current multi-repo commands in the ecosystem (from parent CLAUDE.md):

• /ready-player-one - Orchestrates PR finalization across repos serially
• /fix-pr-ci all - Fixes CI across all PRs but dispatches sequentially
• /sync-main all - Syncs main across all open PRs sequentially
• /auto-claude - Autonomous maintenance that runs serially

These commands process repos one at a time. With 10+ repos, this is slow and can't react to cross-repo dependencies.

Proposed Solution

Team Architecture (team-fix-ci)

/team-fix-ci (team lead - plan approval required)
├── ci-fixer-1 (teammate, plan approval required)
│   ├── Owns: first batch of failing PRs
│   ├── Must get plan approved before making changes
│   └── Messages: lead with fix proposals
├── ci-fixer-2 (teammate, plan approval required)
│   ├── Owns: second batch of failing PRs
│   └── Messages: other fixers about shared dependencies
└── ci-fixer-3 (teammate, plan approval required)
    ├── Owns: third batch of failing PRs
    └── Cross-checks: fixes for conflicts

Key Features

1. Parallel repo processing: Each teammate owns a set of repos
2. Cross-repo awareness: Teammates can message about shared dependencies
3. Plan approval for CI fixes: Lead reviews fix plans before implementation
4. Unified reporting: Reporter teammate aggregates all results
5. Worktree-aware: Teammates work in correct worktree paths

Worktree Integration

Each teammate is spawned with the correct cwd for their repos. The skill documents the worktree structure:

~/git/<repo>/main/           # Always use main worktree for sync
~/git/<repo>/feat/<branch>/  # Use feature worktree for CI fixes

Acceptance Criteria

• /team-sync processes multiple repos in parallel
• /team-fix-ci uses plan approval for safe CI fixes
• Teammates work in correct worktree paths
• Cross-repo dependency detection via messaging
• Unified status report generated
• Graceful fallback to sequential when teams disabled
• Works with the existing worktree structure from CLAUDE.md

Dependencies

• Depends on: agent-teams-orchestrator plugin (feat: create agent-teams-orchestrator plugin with team lifecycle management #15) for lifecycle patterns
