- Add assertSegmentPlanNumAndTargetNodeMatch and
assertChannelPlanNumAndTargetNodeMatch helper functions to validate plan
count and target node membership for unstable assignment tests
- Mark "test assigning channels with resource exhausted nodes" as
unstable since node 2 and 3 have equal priority after filtering
- Replace simple length check with target node validation to ensure
plans assign to expected node set even when order is non-deterministic

Replace the DeduplicateFieldData function with CheckDuplicatePkExist
that returns an error when duplicate primary keys are detected in the
same batch, instead of silently deduplicating.
Changes:
- Replace DeduplicateFieldData with CheckDuplicatePkExist in util.go
- Update upsertTask.PreExecute to return error on duplicate PKs
- Simplify helper function from findLastOccurrenceIndices to
hasDuplicates
- Update unit tests to verify the new error behavior
- Add Python integration tests for duplicate PK error cases

The MultiTargetBalancer was missing replica field assignment in the
generated segment and channel plans, which caused panic during balance
operations. This change ensures that all balance plans have the replica
field properly set to fix the panic issue.
Also refactored the balance test to extract common test logic into a
reusable helper function and added a new integration test specifically
for MultipleTargetBalancer policy.

Previously, mmap settings configured at the collection or field level
were not being applied during segment loading in segcore. This was
caused by:
1. A typo in the key name: "mmap.enable" instead of "mmap.enabled"
2. Missing logic to parse and apply mmap settings from schema
This commit fixes the issue by:
- Correcting the key name to "mmap.enabled" to match the standard
- Adding Schema::MmapEnabled() method to retrieve field/collection level
mmap settings with proper fallback logic
- Parsing mmap settings from field type_params and collection properties
during schema parsing
- Applying computed mmap settings in LoadColumnGroup() and Load()
methods instead of hardcoded false values
- Using global MmapConfig as fallback when no explicit setting exists
The mmap setting priority is now:
1. Field-level mmap setting (from type_params)
2. Collection-level mmap setting (from properties)
3. Global mmap config (from MmapManager)
For column groups, if any field has mmap enabled, the entire group uses
mmap (since they are loaded together).

Follow-up to #45961
After #45961 ensured that handleNodeUp is always called for nodes
discovered during rewatchNodes (including stopping nodes), this change
adds a safeguard in ResourceManager.handleNodeUp to skip adding stopping
nodes to resource groups.
1. **resource_manager.go**: Add check for IsStoppingState() in
handleNodeUp to prevent stopping nodes from being added to incomingNode
set and assigned to resource groups.
2. **server.go**:
- Delete processed nodes from sessionMap to avoid duplicate processing
in the subsequent loop
- Add warning logs for stopping state transitions during rewatch

When QueryCoord restarts or reconnects to etcd, the rewatchNodes
function previously skipped handleNodeUp for QueryNodes in stopping
state. This caused stopping balance to fail because necessary components
were not initialized:
- Task scheduler executor was not added
- Dist handler was not started
- Node was not registered in resource manager
This fix ensures handleNodeUp is always called for new nodes regardless
of their stopping state, followed by handleNodeStopping if the node is
stopping. This allows the graceful shutdown process to correctly migrate
segments and channels away from stopping nodes.

When IndexNodeBinding mode is enabled, DataCoord skips session watching
for datanodes but the dnSessionWatcher field remains nil. This causes a
panic when other code attempts to access the watcher.
This fix introduces an EmptySessionWatcher as a placeholder for the
IndexNodeBinding mode scenario. The empty watcher implements the
SessionWatcher interface with no-op methods, preventing nil pointer
dereferences while maintaining the expected interface contract.

This PR refactors the Loon FFI reader implementation to use
milvus-storage's internal C++ Reader API directly instead of the
external FFI interface.
Key changes:
- Replace external FFI calls (get_record_batch_reader, reader_destroy)
with direct C++ Reader API calls
- Add GetLoonReader() helper function to create Reader instances using
milvus-storage::api::Reader::create()
- Use MakeInternalPropertiesFromStorageConfig() instead of
MakePropertiesFromStorageConfig() to get internal properties
- Update NewPackedFFIReaderWithManifest() to deserialize column groups
from JSON manifest content directly
- Simplify GetFFIReaderStream() to use Reader::get_record_batch_reader()
and arrow::ExportRecordBatchReader() for Arrow stream export
- Change CFFIPackedReader typedef from ReaderHandle to void* for
flexibility
- Update milvus-storage dependency version to ba7df7b
This change improves code maintainability by using the native C++ API
directly and eliminates the overhead of going through the external FFI
layer.

After a collection is successfully loaded, the shard-leader state on the
QC may still not be marked as serviceable. It becomes serviceable only
after the scheduled distribution update runs, which will also invalidate
the shard-leader cache on the proxy. Therefore, even if queries are
already executable, the shard-leader mapping on the proxy may still
change afterward.
Try to ensure—as much as possible—that the proxy’s shard-leader cache
remains stable before killing the mixcoord.
