Adds a syntactic refactoring action that converts implicit raw values to explicit ones for enums whose first inherited type is an integer type (any width up to Int128/UInt128) or String. Resolves #2516. Before: enum Status: Int { case active case inactive case pending = 10 case archived } After: enum Status: Int { case active = 0 case inactive = 1 case pending = 10 case archived = 11 } The action is exposed through `SyntaxRefactoringCodeActionProvider` and performs all transformations as a list of `SourceEdit`s, leaving the rest of the enum (including trailing trivia and member ordering) untouched. ### Motivation: For enums with implicit raw values, making the values explicit is a common refactoring step before serialising the values or relying on their numeric identity. Doing the renumbering by hand is error-prone once any cases already have explicit values, because the implicit continuation rule has to be reapplied for every gap. ### Modifications: - New `Sources/SwiftSyntaxCodeActions/AddExplicitEnumRawValues.swift` conforming to `EditRefactoringProvider` and `SyntaxRefactoringCodeActionProvider`. Handles negative integer literals, hex/binary/octal literals with underscore separators, and backticked case identifiers in String enums. - Registered in `Sources/SwiftSyntaxCodeActions/SyntaxCodeActions.swift` and `Sources/SwiftSyntaxCodeActions/CMakeLists.txt`. - Twelve LSP-level tests in `Tests/SourceKitLSPTests/CodeActionTests.swift` covering positive cases (Int, String, negative continuation, hex continuation, backtick stripping) and negative cases (no raw value type, raw value type not first in inheritance clause, all cases already explicit, unsupported raw value expression, #if directives, freestanding macro expansions, associated value cases). ### Result: When the cursor is on an enum declaration whose raw value type is supported and at least one case is missing an explicit raw value, SourceKit-LSP offers the "Add Explicit Raw Values" code action and inserts the missing raw values in place. The action is suppressed in situations where the implicit numbering cannot be computed safely (unsupported raw value expression, #if blocks, freestanding macros, associated value cases).
