Two shared scaffolds for blocks Sonar flagged across the SqlServer,
Snowflake, and PostgreSQL dialects:
1. **`AppendToClause` on `SqlBreakdownBase`** — collapses the "if
clause is empty set it, else append `{operation} {sql}`; then merge
comment with same rule" pattern that was repeated three times in
each of SqlServer/Snowflake `QueryBreakdown`. The matching
`AddWhereExpression` / `AddHavingExpression` / `AddWhereClause(string)`
sites in both files now delegate to a single `protected static`
helper. Operates against `ISqlClause`, so it works for both the
`WhereClause` and `HavingClause` properties.
2. **`HandleDoubleQuoteAsIdentifier` on `SqlServer.StatementParser`** —
PostgreSQL and Snowflake both override SqlServer's
`HandleDoubleQuote` (which produces a string-literal token) to
instead produce a `ColumnIdentifier` token. The two overrides had
identical 14-line bodies. The shared logic now lives once, and
each dialect's override is a one-liner that calls the helper.
Deliberately *not* refactored in this commit:
- The CTE WITH-clause SQL generation in SqlServer/Snowflake QueryBreakdown
(lines ~537-560 / ~579-601 Sonar flagged) — the surrounding logic
differs enough between the two that an extraction would obscure
rather than clarify.
- The PG/Snowflake QueryBreakdown constructor pair (lines 40-58 /
43-61) — only ~10 lines × 2; extracting requires either a new
shared helper for ~20 lines of savings or moving up the inheritance
chain, neither pays for itself.
All 1180 tests stay green.

- `SqlUtils.cs:43` and `StatementParser.cs:254,285` (CA1861 ×3): inline
`new[] { ' ' }` and `new[] { ';' }` Split delimiters hoisted to
`static readonly char[]` fields next to the existing `separator`
field. Distinct names (`spaceSeparator`, `semicolonSeparator`) avoid
collision.
- `SqlUtils.Filters.cs:27` (CA1806): `double.TryParse(value, out var
dblValue)` had its return value silently discarded — intentional
(downstream switch branches use `dblValue` only when relevant and
rely on the default `0.0` on failure). Now uses `_ =` to make the
discard explicit and extends the comment.
- `FilterCondition.cs:10` and `With.cs:10` (S1135 ×2): rewrite the
`todo:` / `TODO:` markers as plain "Future:" notes. Both comments
documented deliberate design choices ("inherit base for now",
"could be indexed later") rather than tracked work, so the marker
was misleading anyway.

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 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.

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.
