After segments gained self-management capabilities for loading, the
index information from the initial load was not being preserved in the
Go-side segment metadata. This caused QueryCoord to repeatedly dispatch
load index tasks, which would fail in segcore since the indexes were
already loaded.
**Root Cause:**
The segment's `fieldIndexes` map was not being populated with index
metadata after calling `FinishLoad`, leading to a mismatch between the
Go-side metadata and segcore's internal state.
**Solution:**
After successfully loading a sealed segment, iterate through
`loadInfo.IndexInfos` and insert each index entry into the segment's
`fieldIndexes` map. This ensures the Go-side metadata stays in sync with
segcore and prevents redundant load index operations.
