MB-27666: Fix nested mode handling for field-implicit queries (#2272)

- Fix nested-mode search for field-implicit queries (`match_all`,
`docID`): These queries previously filtered nested documents at the
searcher level, but since `ExtractFields` returned no fields, the nested
collector was never activated. In compound queries (e.g., Boolean
filters), this caused a level mismatch—searcher filtering vs
nested-level execution—resulting in zero matches.
- Unify filtering at collector level: Introduced `HasID()` and
`HasAll()` flags in `FieldSet` to track field-implicit queries. Removed
searcher-level filtering from `MatchAllSearcher`.
- Nested collector now correctly activates, ensuring consistent behavior
regardless of query composition.
- Fix an edge case where usage of `match_all query` as a sub-clause in a
`NestedConjunctionSearcher` could cause a panic.
- Fix a case where root document fields would get excluded from the
`_all` field even when included.
- Fix outdated information in `hierarchy.md`
- Add unit tests for Hierarchical Nested Vector Search.
