fix(kanban): clear failure/crash diagnostics while a retry is in flight

A retried task (→ running) kept showing "crashed Nx": the in-flight run
has no outcome yet, so the trailing crash scan skipped it and kept
counting the prior streak, and the consecutive_failures counter lingers.
Exempt `running` from both repeated_failures and repeated_crashes so a
fresh attempt clears the banner until it itself resolves (re-fires if the
new run also fails).
