Support crate analyzer with file resource info, and return used file
resource ids when validate analyzer.
Save the related resource ids in collection schema.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
- Core invariant: analyzer file-resource resolution is deterministic and
traceable by threading a FileResourcePathHelper (collecting used
resource IDs in a HashSet) through all tokenizer/analyzer construction
and validation paths; validate_analyzer(params, extra_info) returns the
collected Vec<i64) which is propagated through C/Rust/Go layers to
callers (CValidateResult → RustResult::from_vec_i64 → Go []int64 →
querypb.ValidateAnalyzerResponse.ResourceIds →
CollectionSchema.FileResourceIds).
- Logic removed/simplified: ad‑hoc, scattered resource-path lookups and
per-filter file helpers (e.g., read_synonyms_file and other inline
file-reading logic) were consolidated into ResourceInfo +
FileResourcePathHelper and a centralized get_resource_path(helper, ...)
API; filter/tokenizer builder APIs now accept &mut
FileResourcePathHelper so all file path resolution and ID collection use
the same path and bookkeeping logic (redundant duplicated lookups
removed).
- Why no data loss or behavior regression: changes are additive and
default-preserving — existing call sites pass extra_info = "" so
analyzer creation/validation behavior and error paths remain unchanged;
new Collection.FileResourceIds is populated from resp.ResourceIds in
validateSchema and round‑tripped through marshal/unmarshal
(model.Collection ↔ schemapb.CollectionSchema) so schema persistence
uses the new list without overwriting other schema fields; proto change
adds a repeated field (resource_ids) which is wire‑compatible (older
clients ignore extra field). Concrete code paths: analyzer creation
still uses create_analyzer (now with extra_info ""), tokenizer
validation still returns errors as before but now also returns IDs via
CValidateResult/RustResult, and rootcoord.validateSchema assigns
resp.ResourceIds → schema.FileResourceIds.
- New capability added: end‑to‑end discovery, return, and persistence of
file resource IDs used by analyzers — validate flows now return resource
IDs and the system stores them in collection schema (affects tantivy
analyzer binding, canalyzer C bindings, internal/util analyzer APIs,
querynode ValidateAnalyzer response, and rootcoord/create_collection
flow).

Move jemalloc_stats.go and its test file from pkg/util/hardware to
internal/util/segcore. This is a more appropriate location because:
- jemalloc_stats depends on milvus_core C++ library via cgo
- The pkg directory should remain independent of internal C++
dependencies
- segcore is the natural home for core memory allocator utilities

Add `Forbidden: true` to all tiered storage related parameters to
prevent runtime configuration changes via etcd. These parameters are
marked as refreshable:"false" but that tag was only documentation - the
actual prevention requires the Forbidden field.
Without this fix, if tiered storage parameters are modified at runtime:
- Go side would read the new values dynamically
- C++ caching layer would still use the old values (set at InitQueryNode
time)
- This mismatch could cause resource tracking issues and anomalies

add ack_sync_up flag into broadcast message header, which indicates that
whether the broadcast operation is need to be synced up between the
streaming node and the coordinator.
If the ack_sync_up is false, the broadcast operation will be acked once
the recovery storage see the message at current vchannel, the fast ack
operation can be applied to speed up the broadcast operation.
If the ack_sync_up is true, the broadcast operation will be acked after
the checkpoint of current vchannel reach current message.
The fast ack operation can not be applied to speed up the broadcast
operation, because the ack operation need to be synced up with streaming
node.
e.g. if truncate collection operation want to call ack once callback
after the all segment are flushed at current vchannel, it should set the
ack_sync_up to be true.
TODO: current implementation doesn't promise the ack sync up semantic,
it only promise FastAck operation will not be applied, wait for 3.0 to
implement the ack sync up semantic. only for truncate api now.

- Add manifest_path field to ImportSegmentInfo for tracking manifest
- Initialize manifest path when creating segments (both import and

- Pass useLoonFFI flag through NewSyncTask in import tasks
- Simplify pack_writer_v2 by removing GetManifestInfo method and relying

- Update segment meta with manifest path after import completion

This PR implements segment reopening functionality on query nodes,
enabling the application of data or schema changes to already-loaded
segments without requiring a full reload.
### Core (C++)
**New SegmentLoadInfo class**
(`internal/core/src/segcore/SegmentLoadInfo.h/cpp`):
- Encapsulates segment load configuration with structured access
- Implements `ComputeDiff()` to calculate differences between old and
new load states
- Tracks indexes, binlogs, and column groups that need to be loaded or
dropped
- Provides `ConvertFieldIndexInfoToLoadIndexInfo()` for index loading
**ChunkedSegmentSealedImpl modifications**:
- Added `Reopen(const SegmentLoadInfo&)` method to apply incremental
changes based on computed diff
- Refactored `LoadColumnGroups()` and `LoadColumnGroup()` to support
selective loading via field ID map
- Extracted `LoadBatchIndexes()` and `LoadBatchFieldData()` for reusable
batch loading logic
- Added `LoadManifest()` for manifest-based loading path
- Updated all methods to use `SegmentLoadInfo` wrapper instead of direct
proto access
**SegmentGrowingImpl modifications**:
- Added `Reopen()` stub method for interface compliance
**C API additions** (`segment_c.h/cpp`):
- Added `ReopenSegment()` function exposing reopen to Go layer
### Go Side
**QueryNode handlers** (`internal/querynodev2/`):
- Added `HandleReopen()` in handlers.go
- Added `ReopenSegments()` RPC in services.go
**Segment interface** (`internal/querynodev2/segments/`):
- Extended `Segment` interface with `Reopen()` method
- Implemented `Reopen()` in LocalSegment
- Added `Reopen()` to segment loader
**Segcore wrapper** (`internal/util/segcore/`):
- Added `Reopen()` method in segment.go
- Added `ReopenSegmentRequest` in requests.go
### Proto
- Added new fields to support reopen in `query_coord.proto`

For a vector field inside a STRUCT, since a STRUCT can only appear as
the element type of an ARRAY field, the vector field in STRUCT is
effectively an array of vectors, i.e. an embedding list.
Milvus already supports searching embedding lists with metrics whose
names start with the prefix MAX_SIM_.
This PR allows Milvus to search embeddings inside an embedding list
using the same metrics as normal embedding fields. Each embedding in the
list is treated as an independent vector and participates in ANN search.
Further, since STRUCT may contain scalar fields that are highly related
to the embedding field, this PR introduces an element-level filter
expression to refine search results.
The grammar of the element-level filter is:
element_filter(structFieldName, $[subFieldName] == 3)
where $[subFieldName] refers to the value of subFieldName in each
element of the STRUCT array structFieldName.
It can be combined with existing filter expressions, for example:
"varcharField == 'aaa' && element_filter(struct_field, $[struct_int] ==
3)"
A full example:
```
struct_schema = milvus_client.create_struct_field_schema()
struct_schema.add_field("struct_str", DataType.VARCHAR, max_length=65535)
struct_schema.add_field("struct_int", DataType.INT32)
struct_schema.add_field("struct_float_vec", DataType.FLOAT_VECTOR, dim=EMBEDDING_DIM)
schema.add_field(
"struct_field",
datatype=DataType.ARRAY,
element_type=DataType.STRUCT,
struct_schema=struct_schema,
max_capacity=1000,
)
...
filter = "varcharField == 'aaa' && element_filter(struct_field, $[struct_int] == 3 && $[struct_str] == 'abc')"
res = milvus_client.search(
COLLECTION_NAME,
data=query_embeddings,
limit=10,
anns_field="struct_field[struct_float_vec]",
filter=filter,
output_fields=["struct_field[struct_int]", "varcharField"],
)
```
TODO:
1. When an `element_filter` expression is used, a regular filter
expression must also be present. Remove this restriction.
2. Implement `element_filter` expressions in the `query`.
