Backports #19098 (3ffe295) to
dev/1.3.Preserve
NO_AVAILABLE_REGION_GROUPthrough LOAD schema analysis and map it toLOAD_TEMPORARY_UNAVAILABLE_EXCEPTION, retaining the TsFile and statement for retry. Permanent metadata errors remain terminal; persistent region loss still requires operator intervention.Adapt the source schema-helper logic to the existing nested 1.3 verifier and use the 1.3
Analysis, statement and TsFile APIs. Preserve type-mismatch conversion priority and port all five source regression scenarios, with an additional regression case for that priority.Target base included in this branch: 91336b6.
