feat(mcp): add durable task runtime foundation (#4665)
* feat(mcp): add durable task runtime foundation

* fix(chart): sync embedded config version

* fix(mcp): isolate task polls during shutdown

* feat(mcp): track consecutive poll errors on mcp_tasks

poll_attempt_count grows on every claim (successful polls included), so it
cannot drive a failure backoff without misjudging normal long tasks. Add
consecutive_poll_error_count: incremented when a claim is released after a
poll error, reset to zero by any applied snapshot. The backoff/terminal
policy that consumes it lands with the first concrete driver.

* fix(mcp): harden durable task lifecycle

* fix(mcp): preserve tracked task on dedup conflict
