Pipeline: auto-recover from deploy failures

When a deploy fails, the pipeline now automatically diagnoses and routes it: transient failures (network timeouts, registry blips) are re-run immediately with no human intervention; code or build errors open a ready-to-build fix ticket; migration conflicts are triaged as either auto-fixable (routine timestamp collision) or human-gated (potentially bad SQL or partial schema drift). Each issue gets one automated recovery attempt before the pipeline hands off to a human, so the factory stays moving without looping forever.
