* fix(mcp): fail durable tasks whose connection no longer resolves
A personal MCP runtime name is derived from the server's complete definition, and a deployment task server belongs to the Gateway startup snapshot. Editing, disabling, or deleting a personal server while a durable task is in flight therefore makes the persisted server name unresolvable. McpTaskToolCaller raised LookupError, which the service classifies as transient: status polls and cancellation retried forever, leaving the task stuck in working and impossible to cancel.
Raise a dedicated McpTaskConnectionUnavailableError instead, and terminalize it: status polls persist failed with the connection error and stop; a pending cancellation persists failed locally because the remote task can no longer be reached. Transient status/cancel errors keep their existing capped-backoff retry policy.
Tests: new service tests pin both terminal paths, and caller tests pin the exception for missing deployment and stale personal server names.
* fix(mcp): preserve LookupError compatibility for connection errors
McpTaskConnectionUnavailableError now subclasses LookupError instead of RuntimeError. The four existing personal-MCP assertions in test_personal_mcp.py still treat a missing or stale connection as a lookup failure; keeping that base preserves their behavior and avoids breaking callers that caught the previous type, while the task service still catches this exact type for permanent-failure classification.
Add a compatibility test and rerun the personal-MCP and task suites.

* fix(mcp): isolate pooled sessions by ownership domain
Separate deployment and personal stdio sessions even when they share the same runtime server name and thread scope. Preserve deployment call compatibility while carrying personal ownership through Agent wrappers, durable task calls, and disconnect eviction.
Add focused regression coverage for personal discovery wiring and domain-scoped disconnect cleanup.
* test(mcp): address ownership-domain review feedback
Accept the new wrapper keyword in the prefix-overlap test double and reuse MCPPoolDomain for internal task-caller ownership parameters.
* style(mcp): format ownership-domain changes

* 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.
