enhance: [StorageV2] add manifest path support for FFI integration (#44991)
Related to #44956

Add manifest_path field throughout the data path to support LOON Storage
V2 manifest tracking. The manifest stores metadata for segment data
files and enables the unified Storage V2 FFI interface.

Changes include:
- Add manifest_path field to SegmentInfo and SaveBinlogPathsRequest
proto messages
- Add UpdateManifest operator to datacoord meta operations
- Update metacache, sync manager, and meta writer to propagate manifest
paths
- Include manifest_path in segment load info for query coordinator

This is part of the Storage V2 FFI interface integration.

enhance: forbid build analyzer at proxy (#44067)
relate: https://github.com/milvus-io/milvus/issues/43687
We used to run the temporary analyzer and validate analyzer on the
proxy, but the proxy should not be a computation-heavy node. This PR
move all analyzer calculations to the streaming node.

feat: support dropping index without releasing collection (#42941)
issue: #42942

This pr includes the following changes:
1. Added checks for index checker in querycoord to generate drop index
tasks
2. Added drop index interface to querynode
3. To avoid search failure after dropping the index, the querynode
allows the use of lazy mode (warmup=disable) to load raw data even when
indexes contain raw data.
4. In segcore, loading the index no longer deletes raw data; instead, it
evicts it.
5. In expr, the index is pinned to prevent concurrent errors.

enhance: Refine QueryNode task parallelism based on CPU core count (#42166)
issue: #42165
Implement dynamic task execution capacity calculation based on QueryNode
CPU core count instead of static configuration for better resource
utilization.

Changes include:
- Add CpuCoreNum() method and WithCpuCoreNum() option to NodeInfo
- Implement GetTaskExecutionCap() for dynamic capacity calculation
- Add QueryNodeTaskParallelismFactor parameter for tuning
- Update proto definition to include cpu_core_num field
- Add unit tests for new functionality

This allows QueryCoord to automatically adjust task parallelism based on
actual hardware resources.

feat: Implement partial result support on node down (#42009)
issue: https://github.com/milvus-io/milvus/issues/41690
This commit implements partial search result functionality when query
nodes go down, improving system availability during node failures. The
changes include:

- Enhanced load balancing in proxy (lb_policy.go) to handle node
failures with retry support
- Added partial search result capability in querynode delegator and
distribution logic
- Implemented tests for various partial result scenarios when nodes go
down
- Added metrics to track partial search results in querynode_metrics.go
- Updated parameter configuration to support partial result required
data ratio
- Replaced old partial_search_test.go with more comprehensive
partial_result_on_node_down_test.go
- Updated proto definitions and improved retry logic

These changes improve query resilience by returning partial results to
users when some query nodes are unavailable, ensuring that queries don't
completely fail when a portion of data remains accessible.

enhance: Optimize shard serviceable mechanism (#41937)
issue: https://github.com/milvus-io/milvus/issues/41690
- Merge leader view and channel management into ChannelDistManager,
allowing a channel to have multiple delegators.
- Improve shard leader switching to ensure a single replica only has one
shard leader per channel. The shard leader handles all resource loading
and query requests.
- Refine the serviceable mechanism: after QC completes loading, sync the
query view to the delegator. The delegator then determines its
serviceable status based on the query view.
- When a delegator encounters forwarding query or deletion failures,
mark the corresponding segment as offline and transition it to an
unserviceable state.
