Implement partial field update functionality for upsert operations,
supporting scalar, vector, and dynamic JSON fields without requiring all
collection fields.
Changes:
- Add queryPreExecute to retrieve existing records before upsert
- Implement UpdateFieldData function for merging data
- Add IDsChecker utility for efficient primary key lookups
- Fix JSON data creation in tests using proper map marshaling
- Add test cases for partial updates of different field types

Ref #42053
This is the first PR for optimizing `LIKE` with ngram inverted index.
Now, only VARCHAR data type is supported and only InnerMatch LIKE
(%xxx%) query is supported.
How to use it:
```
milvus_client = MilvusClient("http://localhost:19530")
schema = milvus_client.create_schema()
...
schema.add_field("content_ngram", DataType.VARCHAR, max_length=10000)
...
index_params = milvus_client.prepare_index_params()
index_params.add_index(field_name="content_ngram", index_type="NGRAM", index_name="ngram_index", min_gram=2, max_gram=3)
milvus_client.create_collection(COLLECTION_NAME, ...)
```
min_gram and max_gram controls how we tokenize the documents. For
example, for min_gram=2 and max_gram=4, we will tokenize each document
with 2-gram, 3-gram and 4-gram.

Previously the `CollectionTtlTimestamp` could be overflowed when the
guarantee_ts==1, which means using `Eventually` consistency level.
This patch use task timestamp, allocated by scheduler, to generate ttl
timestamp ignore the potential very small timestamp being used.
Also add overflow check for ttl timestamp calculated.

issue: #42098#42404
Fix critical issue where concurrent balance segment and balance channel
operations cause delegator view inconsistency. When shard leader
switches between load and release phases of segment balance, it results
in loading segments on old delegator but releasing on new delegator,
making the new delegator unserviceable.
The root cause is that balance segment modifies delegator views, and if
these modifications happen on different delegators due to leader change,
it corrupts the delegator state and affects query availability.
Changes include:
- Add shardLeaderID field to SegmentTask to track delegator for load
- Record shard leader ID during segment loading in move operations
- Skip release if shard leader changed from the one used for loading
- Add comprehensive unit tests for leader change scenarios
This ensures balance segment operations are atomic on single delegator,
preventing view corruption and maintaining delegator serviceability.

Move the exclude nodes clearing logic from ExecuteWithRetry to
selectNode after shard leader cache refresh to ensure proper retry
behavior:
- Remove premature exclude clearing in ExecuteWithRetry that happened
before shard leader cache update
- Add exclude clearing logic in selectNode after refreshing shard leader
cache when all replicas are excluded
- Ensure multiple retries can properly update shard leader cache and
clear exclude list when needed
- Add comprehensive tests for edge cases including empty shard leaders
and mixed serviceable node scenarios
