feat(team): team enhancements, subagentModel, parallel tool exec

Port the agent-team enhancement layer onto upstream/main so the model
can spin up coordinated sub-agent teams for parallel work.

subagentModel config wiring (fix):
- Add subagent_model field to RuntimeFeatureConfig + RuntimeConfig::subagent_model()
  accessor so the subagentModel setting (already validated by config_validate.rs)
  is now actually read and stored.
- Agent tool's resolve_agent_model falls back to subagentModel from config
  when no explicit model is passed.

Provider namespace separation:
- New 'custom-openai' provider kind with dedicated env vars
  (CLAWCUSTOMOPENAI_API_KEY / CLAWCUSTOMOPENAI_BASE_URL)
- /setup wizard saves kind: 'custom-openai' for option 5
- Bare model name normalized to 'custom/' prefix to avoid proxy 404s
- Sub-agents inherit /setup-saved provider config via inject_config_as_env_fallbacks

Parallel tool execution:
- Override execute_batch to classify read-only tools as parallel-safe
  and run them concurrently via std::thread::scope
- Results return in original model order

Team coordination layer:
- AgentMessage, TaskClaim, TeamStatus tools + shared mailbox directory
- Mode presets (tiny/1x ... mega/6x) + enriched TeamCreate/Agent descriptions
- Background team watcher
- /team slash command: on/off/status/toggle

# Multi-Tool Execution & Sub-Agent Delegation
Two complementary features that dramatically reduce latency and token usage when the model needs to perform multiple operations or gather context.
## Feature 1: Parallel Tool Execution
When the model returns multiple tool_use blocks in a single response, read-only tools now execute concurrently instead of sequentially.
### How it works
The `run_turn` loop is refactored into 3 phases:
1. **Pre-hooks + permission checks** (sequential — hooks may mutate state)
2. **Tool execution** (batch — parallel for read-only tools via `std::thread::scope`)
3. **Post-hooks + session updates** (sequential — preserves original ordering)
### Parallel-safe tools
These tools are safe to run concurrently because they only read state and dispatch through the stateless tool registry:
- `read_file`, `glob_search`, `grep_search`
- `WebFetch`, `WebSearch`
- `ToolSearch`, `Skill`
- `LSP`
- `GitStatus`, `GitDiff`, `GitLog`, `GitShow`, `GitBlame`
### Sequential-only tools
Tools that require `&mut self` or have side effects continue to run one at a time:
- `bash`, `write_file`, `edit_file` (side effects)
- `MCP`, `McpAuth`, `RemoteTrigger` (network state)
- `Agent`, `TaskCreate`, `WorkerCreate` (stateful)
- `NotebookEdit`, `REPL`, `PowerShell` (side effects)
### Safety guarantees
- Pre/post hooks always run sequentially
- Permission checks complete before any tool executes
- Tool results are pushed to the session in the original model order
- Falls back to sequential for single-tool batches
- Thread scopes ensure all parallel work completes before `execute_batch` returns
### Impact
For a response with 5 `read_file` calls: **~5x faster** execution. The main model still sees all results in order.
---
## Feature 2: SubAgent Delegation
A `SubAgent` tool that lets the main model delegate multi-step tasks to a fast sub-agent. The sub-agent runs autonomously with its own `ConversationRuntime`, making multiple tool calls without round-tripping through the main model.
### Tool parameters
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `prompt` | string | yes | Task description for the sub-agent |
| `task_type` | string | no | `Explore` (default), `Plan`, or `Verify` |
| `model` | string | no | Override the sub-agent model |
### Task types
| Type | Available tools | Use for |
|------|----------------|---------|
| `Explore` | read_file, glob_search, grep_search, WebFetch, WebSearch, ToolSearch, StructuredOutput | Searching code, reading files, gathering context |
| `Plan` | Explore + TodoWrite | Planning approaches with structured todo output |
| `Verify` | Plan + bash | Running tests, checking builds, verifying changes |
### Configuration
Set the sub-agent model in `~/.claw/settings.json`:
```json
{
"model": "openai/glm-5.1-fast",
"subagentModel": "openai/qwen3.6-35b-fast"
}
```
If `subagentModel` is not set, the sub-agent uses the same model as the main session (or the `model` override parameter on the tool call).
### Example
Main model prompt: "Find all Rust files that import `ConversationRuntime` and list their paths"
Without SubAgent: 5–10 sequential tool calls (grep → read each file → summarize)
With SubAgent: 1 SubAgent call → sub-agent does all the work autonomously → returns summary
**Result**: ~10x fewer tokens consumed by the main model, faster overall completion.
### Architecture
The sub-agent reuses the same building blocks as the existing `Agent` tool:
- `ProviderRuntimeClient` — API client with fallback chain
- `SubagentToolExecutor` — filtered tool access with permission enforcement
- `ConversationRuntime` — full conversation loop with hooks and compaction
- `agent_permission_policy()` — auto-approve read-only, deny write tools
Key differences from the `Agent` tool:
- **Synchronous** — blocks until complete, returns result directly
- **Lighter** — fewer default tools, focused on the task type
- **Configurable model** — uses `subagentModel` or the tool's `model` param
- **Structured output** — returns `result`, `tool_calls`, and `iterations`
