N coordinated agents on shared task list using Claude Code native teams

# Team Skill

Spawn N coordinated agents working on a shared task list using Claude Code's native team tools. Replaces the legacy `/swarm` skill (SQLite-based) with built-in team management, inter-agent messaging, and task dependencies -- no external dependencies required.

The `swarm` compatibility alias was removed in #1131.

## Usage

```
/oh-my-claudecode:team N:agent-type "task description"
/oh-my-claudecode:team "task description"
/oh-my-claudecode:team ralph "task description"
```

### Parameters

- **N** - Number of teammate agents (1-20). Optional; defaults to auto-sizing based on task decomposition.
- **agent-type** - OMC agent to spawn for the `team-exec` stage (e.g., executor, debugger, designer, codex, gemini). Optional; defaults to stage-aware routing. Use `codex` to spawn Codex CLI workers or `gemini` for Gemini CLI workers (requires respective CLIs installed). See Stage Agent Routing below.
- **task** - High-level task to decompose and distribute among teammates
- **ralph** - Optional modifier. When present, wraps the team pipeline in Ralph's persistence loop (retry on failure, architect verification before completion). See Team + Ralph Composition below.

### Examples

```bash
/team 5:executor "fix all TypeScript errors across the project"
