A resumed leg that runs longer than its pointer's wall-clock TTL stranded
_lookup_task on the base leg (false completion / not found). Each poll now
refreshes the routing keys' TTL (sliding expiration), so an actively-polled
task keeps them alive regardless of execution duration, and the resumed-leg
write uses the same buffered TTL as creation. Separately, remote-worker server
resolution now respects the requested tool version, so two versions of the same
mounted tool name resolve to their own child server.
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.
