Expanded C# 14 extension bodies unnecessarily replaced accessible named constants with cast literals and wrapped object creation expressions in parentheses. Preserve constant references when they are accessible from the generated output type, while continuing to inline inaccessible constants, and omit redundant parentheses around explicit object creation. Target-typed creation is normalized to explicit creation before this check; return conversion casts retain their parentheses.

Adds regression coverage for qualified and unqualified constants, public/internal/private accessibility, explicit and target-typed object creation, member access, and adapted extension helpers using a rounding constant. Runtime tests also verify interface return conversions with explicit interface implementation and user-defined implicit conversions, both directly and before member access. Includes the 0.8.2 version bump and corresponding generated-code version snapshots.

Validation:

• Release solution build and full solution tests passed: 224 succeeded, 0 failed, 0 skipped.
• git diff --check passed.
• Before the final condition narrowing and conversion tests, NuGet packing with --no-build --no-restore and compiler/package compatibility checks passed for Roslyn 4.8.0, 4.14.0, 5.0.0, and the installed SDK.
