feat: add remaining tool specs — Team, Cron, LSP, MCP, RemoteTrigger
Port 10 more missing tool definitions from upstream parity audit:
- TeamCreate, TeamDelete: parallel sub-agent team management
- CronCreate, CronDelete, CronList: scheduled recurring tasks
- LSP: Language Server Protocol code intelligence queries
- ListMcpResources, ReadMcpResource, McpAuth: MCP server resource access
- RemoteTrigger: remote action/webhook triggers
All tools have full ToolSpec schemas and stub execute functions.
Tool surface now 38/40 (was 28/40). Remaining: MCPTool (dynamic
tool proxy) and TestingPermissionTool (test-only).
fmt/clippy/tests all green.
