[2.30.0] Add orchestrating-swarms skill, /slfg command, and swarm mode (#151)

- New skill: orchestrating-swarms — comprehensive guide to multi-agent
  swarm orchestration with TeammateTool operations, spawn backends,
  task dependencies, and orchestration patterns
- New command: /slfg — swarm-enabled variant of /lfg that parallelizes
  review + browser tests after work phase, then resolves and records video
- Updated /workflows:work with optional Swarm Mode section
- Added missing skills (brainstorming, orchestrating-swarms) to README
- Added missing commands (/lfg, /slfg) to README

+description: Full autonomous engineering workflow using swarm mode for parallel execution

+
+Swarm-enabled LFG. Run these steps in order, parallelizing where indicated.
+
+## Sequential Phase
+
+1. `/ralph-wiggum:ralph-loop "finish all slash commands" --completion-promise "DONE"`
+2. `/workflows:plan $ARGUMENTS`
+3. `/compound-engineering:deepen-plan`
+4. `/workflows:work` — **Use swarm mode**: Make a Task list and launch an army of agent swarm subagents to build the plan
+
+## Parallel Phase
+
+After work completes, launch steps 5 and 6 as **parallel swarm agents** (both only need code to be written):
+
+5. `/workflows:review` — spawn as background Task agent
+6. `/compound-engineering:test-browser` — spawn as background Task agent
+
+Wait for both to complete before continuing.
+
+## Finalize Phase
+
+7. `/compound-engineering:resolve_todo_parallel` — resolve any findings from the review
+8. `/compound-engineering:feature-video` — record the final walkthrough and add to PR
+9. Output `<promise>DONE</promise>` when video is in PR
+
+Start with step 1 now.

+## Swarm Mode (Optional)
+
+For complex plans with multiple independent workstreams, enable swarm mode for parallel execution with coordinated agents.
+
+### When to Use Swarm Mode
+
+| Use Swarm Mode when... | Use Standard Mode when... |
+|------------------------|---------------------------|
+| Plan has 5+ independent tasks | Plan is linear/sequential |
+| Multiple specialists needed (review + test + implement) | Single-focus work |
+| Want maximum parallelism | Simpler mental model preferred |
+| Large feature with clear phases | Small feature or bug fix |
+
+### Enabling Swarm Mode
+
+To trigger swarm execution, say:
+
+> "Make a Task list and launch an army of agent swarm subagents to build the plan"
+
+Or explicitly request: "Use swarm mode for this work"
+
+### Swarm Workflow
+
+When swarm mode is enabled, the workflow changes:
+
+1. **Create Team**
+   ```
+   Teammate({ operation: "spawnTeam", team_name: "work-{timestamp}" })
+   ```
+
+2. **Create Task List with Dependencies**
+   - Parse plan into TaskCreate items
+   - Set up blockedBy relationships for sequential dependencies
+   - Independent tasks have no blockers (can run in parallel)
+
+3. **Spawn Specialized Teammates**
+   ```
+   Task({
+     team_name: "work-{timestamp}",
+     name: "implementer",
+     subagent_type: "general-purpose",
+     prompt: "Claim implementation tasks, execute, mark complete",
+     run_in_background: true
+   })
+
+   Task({
+     team_name: "work-{timestamp}",
+     name: "tester",
+     subagent_type: "general-purpose",
+     prompt: "Claim testing tasks, run tests, mark complete",
+     run_in_background: true
+   })
+   ```
+
+4. **Coordinate and Monitor**
+   - Team lead monitors task completion
+   - Spawn additional workers as phases unblock
+   - Handle plan approval if required
+
+5. **Cleanup**
+   ```
+   Teammate({ operation: "requestShutdown", target_agent_id: "implementer" })
+   Teammate({ operation: "requestShutdown", target_agent_id: "tester" })
+   Teammate({ operation: "cleanup" })
+   ```
+
+See the `orchestrating-swarms` skill for detailed swarm patterns and best practices.
