A FastMCP client now transparently completes tasked tools/call: the tasks
ClientExtension advertises the capability and claims the CreateTaskResult, and
the resolver drives the tasks/get poll loop to completion, answering in-task
input through the client's elicitation handler and returning the tool's real
result. call_tool is transparent, call_tool_mcp exposes the raw result, and
call_tool_task yields a Task handle. The client half moves to fastmcp-tasks;
the [tasks] client extension auto-wires into Client (ProxyClient opts out).

TasksExtension serves io.modelcontextprotocol/tasks on the extension API:
a decide-and-task tools/call interceptor (era-gated to modern connections),
tasks/get with inlined results and inputRequests, tasks/update delivering
poll-based in-task elicitation, tasks/cancel, durable creation, and
auth-scoped task isolation. Wire models validate against the vendored
ext-tasks schema. Worker-side Context hooks are refcounted so sibling
servers cannot strand each other's workers.

Engine modules (keys, context snapshot, docket lifespan, worker CLI,
client handles) move intact; SEP-1686 wire modules park in _legacy_wire
for adaptation to SEP-2663. Core keeps task=True declaration on tools
only and raises at serve time until the tasks extension is registered.
