3859cc8699 fix: deduplicate doc counts in term aggregation for multi-valued fields (#2854) 
* fix: deduplicate doc counts in term aggregation for multi-valued fields

Term aggregation was counting term occurrences instead of documents
for multi-valued fields. A document with the same value appearing
multiple times would inflate doc_count.

Add `fetch_block_with_missing_unique_per_doc` to ColumnBlockAccessor
that deduplicates (doc_id, value) pairs, and use it in term aggregation.

Fixes #2721

* refactor: only deduplicate for multivalue cardinality

Duplicates can only occur with multivalue columns, so narrow the
check from !is_full() to is_multivalue().

* fix: handle non-consecutive duplicate values in dedup

Sort values within each doc_id group before deduplicating, so that
non-adjacent duplicates are correctly handled.

Add unit tests for dedup_docid_val_pairs: consecutive duplicates,
non-consecutive duplicates, multi-doc groups, no duplicates, and
single element.

* perf: skip dedup when block has no multivalue entries

Add early return when no consecutive doc_ids are equal, avoiding
unnecessary sort and dedup passes. Remove the 2-element swap
optimization as it is not needed by the dedup algorithm.

1251b40c93 Drop use_serde feature; use Java binary encoding for PercentilesCollector 
Replace the derived Serialize/Deserialize on PercentilesCollector with
custom impls that use DDSketch's Java-compatible binary encoding
(encode_to_java_bytes / decode_from_java_bytes). This removes the need
for the use_serde feature on sketches-ddsketch entirely.

Also restore original float test values and use assert_nearly_equals!
for all float comparisons in percentile tests, since DDSketch quantile
estimates can have minor precision differences across platforms.

68626bf3a1 Vendor sketches-ddsketch with Java-compatible binary encoding 
Fork sketches-ddsketch as a workspace member to add native Java binary
serialization (to_java_bytes/from_java_bytes) for DDSketch. This enables
pomsky to return raw DDSketch bytes that event-query can deserialize via
DDSketchWithExactSummaryStatistics.decode().

Key changes:
- Vendor sketches-ddsketch crate with encoding.rs implementing VarEncoding,
  flag bytes, and INDEX_DELTAS_AND_COUNTS store format
- Align Config::key() to floor-based indexing matching Java's LogarithmicMapping
- Add PercentilesCollector::to_sketch_bytes() for pomsky integration
- Cross-language golden byte tests verified byte-identical with Java output

cdd24b7ee5 Replace hyperloglogplus with Apache DataSketches HLL (lg_k=11) 
Switch tantivy's cardinality aggregation from the hyperloglogplus crate
(HyperLogLog++ with p=16) to the official Apache DataSketches HLL
implementation (datasketches crate v0.2.0 with lg_k=11, Hll4).

This enables returning raw HLL sketch bytes from pomsky to Datadog's
event query, where they can be properly deserialized and merged using
the same DataSketches library (Java). The previous implementation
required pomsky to fabricate fake HLL sketches from scalar cardinality
estimates, which produced incorrect results when merged.

Changes:
- Cargo.toml: hyperloglogplus 0.4.1 -> datasketches 0.2.0
- CardinalityCollector: HyperLogLogPlus<u64, BuildSaltedHasher> -> HllSketch
- Custom Serde impl using HllSketch binary format (cross-shard compat)
- New to_sketch_bytes() for external consumers (pomsky)
- Salt preserved via (salt, value) tuple hashing for column type disambiguation
- Removed BuildSaltedHasher struct
- Added 4 new unit tests (serde roundtrip, merge, binary compat, salt)

# Update Changelog
This skill updates CHANGELOG.md with merged PRs that aren't already listed.
## Step 1: Determine the changelog scope
Read `CHANGELOG.md` to identify the current unreleased version section at the top (e.g., `Tantivy 0.26 (Unreleased)`).
Collect all PR numbers already mentioned in the unreleased section by extracting `#NNNN` references.
## Step 2: Find merged PRs not yet in the changelog
Use `gh` to list recently merged PRs from the upstream repo:
```bash
gh pr list --repo quickwit-oss/tantivy --state merged --limit 100 --json number,title,author,labels,mergedAt
```
Filter out any PRs whose number already appears in the unreleased section of the changelog.
## Step 3: Consolidate related PRs
Before categorizing, group PRs that belong to the same logical change. This is critical for producing a clean changelog. Use PR descriptions, titles, cross-references, and the files touched to identify relationships.
**Merge follow-up PRs into the original:**
- If a PR is a bugfix, refinement, or follow-up to another PR in the same unreleased cycle, combine them into a single changelog entry with multiple `[#N](url)` links.
- Also consolidate PRs that touch the same feature area even if not explicitly linked — e.g., a PR fixing an edge case in a new API should be folded into the entry for the PR that introduced that API.
**Filter out bugfixes on unreleased features:**
- If a bugfix PR fixes something introduced by another PR in the **same unreleased version**, it must NOT appear as a separate Bugfixes entry. Instead, silently fold it into the original feature/improvement entry. The changelog should describe the final shipped state, not the development history.
- To detect this: check if the bugfix PR references or reverts changes from another PR in the same release cycle, or if it touches code that was newly added (not present in the previous release).
## Step 4: Review the actual code diff
**Do not rely on PR titles or descriptions alone.** For every candidate PR, run `gh pr diff <number> --repo quickwit-oss/tantivy` and read the actual changes. PR titles are often misleading — the diff is the source of truth.
**What to look for in the diff:**
- Does it change observable behavior, public API surface, or performance characteristics?
- Is the change something a user of the library would notice or need to know about?
- Could the change break existing code (API changes, removed features)?
**Skip PRs where the diff reveals the change is not meaningful enough for the changelog** — e.g., cosmetic renames, trivial visibility tweaks, test-only changes, etc.
## Step 5: Categorize each PR group
For each PR (or consolidated group) that survived the diff review, determine its category:
- **Bugfixes** — fixes to behavior that existed in the **previous release**. NOT fixes to features introduced in this release cycle.
- **Features/Improvements** — new features, API additions, new options, improvements that change user-facing behavior or add new capabilities.
- **Performance** — optimizations, speed improvements, memory reductions. **If a PR adds new API whose primary purpose is enabling a performance optimization, categorize it as Performance, not Features.** The deciding question is: does a user benefit from this because of new functionality, or because things got faster/leaner? For example, a new trait method that exists solely to enable cheaper intersection ordering is Performance, not a Feature.
If a PR doesn't clearly fit any category (e.g., CI-only changes, internal refactors with no user-facing impact, dependency bumps with no behavior change), skip it — not everything belongs in the changelog.
When unclear, use your best judgment or ask the user.
## Step 6: Format entries
Each entry must follow this exact format:
```
- Description [#NUMBER](https://github.com/quickwit-oss/tantivy/pull/NUMBER)(@author)
```
Rules:
- The description should be concise and describe the user-facing change (not the implementation). Describe the final shipped state, not the incremental development steps.
- Use sub-categories with bold headers when multiple entries relate to the same area (e.g., `- **Aggregation**` with indented entries beneath). Follow the existing grouping style in the changelog.
- Author is the GitHub username from the PR, prefixed with `@`. For consolidated entries, include all contributing authors.
- For consolidated PRs, list all PR links in a single entry: `[#100](url) [#110](url)` (see existing entries for examples).
## Step 7: Present changes to the user
Show the user the proposed changelog entries grouped by category **before** editing the file. Ask for confirmation or adjustments.
## Step 8: Update CHANGELOG.md
Insert the new entries into the appropriate sections of the unreleased version block. If a section doesn't exist yet, create it following the order: Bugfixes, Features/Improvements, Performance.
Append new entries at the end of each section (before the next section header or version header).
## Step 9: Verify
Read back the updated unreleased section and display it to the user for final review.
