Replaces `null` returns from `SqlBreakdownBase.GetQuery<T>()` and its four
overrides (LinqQueryBreakdown, SqlServer/PostgreSql/Snowflake QueryBreakdown)
with `Enumerable.Empty<T>().AsQueryable()`, and tightens the signature from
`IQueryable<T>?` to `IQueryable<T>`. The "we can't reconstruct" semantic
now lives in "the query yields zero rows" rather than a nullable return,
which is what callers in LINQ pipelines actually want.
Three LinqQueryBreakdownTests tests asserting `Is.Null` are renamed and
updated to assert `Is.Empty`.
BREAKING CHANGE: SqlBreakdownBase.GetQuery<T> and the SqlServer / PostgreSql /
Snowflake / LinqToSql QueryBreakdown.GetQuery<T> overrides no longer return
`IQueryable<T>?`; they now return a non-nullable `IQueryable<T>` that is
empty when reconstruction isn't possible. External NuGet consumers null-
checking the result must switch to `.Any()` / `Is.Empty` checks instead.

Manual sweep of all 42 IDE0028 sites flagged by SonarQube — `dotnet format
analyzers --diagnostics IDE0028` declined to fix these (no .editorconfig
opt-in for `dotnet_style_prefer_collection_expression`), so applied by
hand. The repo already targets `<LangVersion>latest</LangVersion>` on
net8.0, so C# 12 collection expressions are available.
Pattern: `new List<T>()` / `new Dictionary<K,V>()` / `new ArrayList()` /
`new()` -> `[]` for empty; `new List<T> { ... }` -> `[...]` for literal.
24 files touched in src/{EFCore, LinqToSql, Query, Snowflake, SqlBreakdown,
SqlServer}; tests untouched (no IDE0028 sites in test code).
Build clean (35 warnings unchanged from baseline, 0 errors). All tests
remain green.

Applied via `dotnet format analyzers --diagnostics CA1854 --severity info`.
Eliminates the duplicate hash lookup in the
`if (d.ContainsKey(k)) d[k]++ else d[k] = 1` pattern. The fixer rewrites
the conditional to `if (d.TryGetValue(k, out var value)) d[k] = ++value;`
which is semantically identical but does the lookup once.
4 files touched.

Applied via `dotnet format analyzers --diagnostics CA1861 --severity info`,
plus manual cleanup:
- Renamed two cryptic fixer-generated field names:
- QueryBreakdownCollection.stringArray -> SnowflakeFunctionNames (and
inlined the now-redundant local alias)
- ExpressionObjectTests.arg2 -> NotInValues
- Deduped three identical `separator = ['\r','\n']` fields the fixer
emitted in the same test class (kept the first declaration; the other
two test methods now reuse it).
8 files touched.

Applied via `dotnet format analyzers --diagnostics CA1510 --severity info`.
Replaces `if (x == null) throw new ArgumentNullException(nameof(x));`
blocks with the one-line `ArgumentNullException.ThrowIfNull(x);` —
same behavior, same parameter name, much less noise.
6 files touched across SqlBreakdown, SqlServer, LinqToSql.

S2342 requires [Flags] enums to use plural names. Both enums have zero
references anywhere in the repo today.
- ConstraintType -> ConstraintTypes
- TriggerType -> TriggerTypes
BREAKING CHANGE: external NuGet consumers (if any) referencing these
singular-named types will need to update to the plural names. Internal
codebase has no references.

- WithClause.RecursiveQuery and WithClause.ColumnList had get/set bodies that
only forwarded to private backing fields. Convert both to auto-properties
and remove the now-orphaned _recursiveQuery / _columnList fields.

The `[Serializable]` attribute and corresponding `[OnDeserialized]` methods have been removed from various breakdown classes. This eliminates reliance on `BinaryFormatter`, which is a deprecated and insecure serialization mechanism in modern .NET.
This change also resolves SonarQube rule S5766 warnings by removing the context in which they apply, leading to cleaner and more secure code.
Introduce a default regex match timeout across the library to prevent potential ReDoS attacks (SonarQube rule S6444).
Implement `[OnDeserialized]` methods to re-establish object invariants and validate state after deserialization, addressing SonarQube rule S5766.
Resolves SonarQube S2365 x3.
CalculationFilterGroup (Snowflake + SqlServer): the `Filters` getter
ran .Where(...).ToList() on every access. Convert to a plain
auto-property holding the raw collection plus a `GetValidFilters()`
method that does the filtering. Update internal IsValid() and the two
QueryConfigExtensions callers to use the new method.
HierarchicalData.AllChildData: part of the IHierarchicalData interface
and JSON-serialized; the transformation IS the property's contract.
Suppress S2365 with justification rather than refactor -- same pattern
as S3875.
Behavior change: CalculationFilterGroup JSON output now serializes the
raw filter collection rather than the pre-filtered one. Round-trip is
preserved; callers needing the filtered view must call GetValidFilters().
