feat(coding-agent): stop waiting for MCP servers on the first prompt

The first prompt waits only for servers with direct tools. Other servers
connect in the background; codemode scripts, tool_search, and the
resource tools wait for the servers they need. codemode and tool_search
are activated from the config.

Tool declarations no longer depend on connected servers: the codemode
description leaves out deferred tools, and the tool_search description
no longer lists sources. Servers are listed in an mcp_servers system
prompt section instead, set in before_agent_start from the config and
connected state, so changes are appended to the conversation.

describeNamespace() and searchTools() accept mcp__dev-radius,
mcp__dev_radius, dev-radius, and dev_radius.

A tool that orchestrates other tools can adjust what the model sees while it is active with `prepareLoadout(loadout)`. It runs whenever the active tools change and receives the declared tools, the callable tools, and every registered tool with its exposure and namespace. It returns replacement `descriptions` for declared tools (including its own) and `hiddenDeclarations`: active tools whose declarations requests leave out while they stay active and callable. `codemode` and `tool_search` use only this hook, `exposure`, and `ctx.executeTool()`, so another tool can implement the same behavior under a different name.
