…ing-valued enums, plus int-valued as a bonus).
- `Plugins/BridgeJS/Sources/TS2Swift/JavaScript/src/processor.js`: emits Swift `enum Name: String { ... }` (or `: Int`) for TS enums, adds `extension Name: _BridgedSwiftEnumNoPayload {}`, and ensures enum-typed parameters/returns stay typed as the enum (not downgraded to `String`).
- `Plugins/BridgeJS/Sources/BridgeJSCore/ImportSwiftMacros.swift`: resolves referenced Swift enums/typealiases via `TypeDeclResolver` so `FeatureFlag` becomes `.rawValueEnum("FeatureFlag", .string)` in the imported skeleton.
- `Plugins/BridgeJS/Sources/BridgeJSCore/ImportTS.swift`: enables lowering/lifting for `.rawValueEnum` in the `.importTS` context (parameters + returns).
- Added coverage: `Plugins/BridgeJS/Tests/BridgeJSToolTests/Inputs/StringEnum.d.ts` with new snapshots `Plugins/BridgeJS/Tests/BridgeJSToolTests/__Snapshots__/ImportTSTests/StringEnum.Macros.swift` and `Plugins/BridgeJS/Tests/BridgeJSToolTests/__Snapshots__/ImportTSTests/StringEnum.swift`.
- Verified with `swift test --package-path ./Plugins/BridgeJS --filter ImportTSTests`.
- Updated `Tests/BridgeJSRuntimeTests/bridge-js.d.ts` with `FeatureFlag` + `jsRoundTripFeatureFlag`. - Added JS implementation in `Tests/prelude.mjs`. - Added XCTest in `Tests/BridgeJSRuntimeTests/ImportAPITests.swift` (`testRoundTripFeatureFlag`). - Regenerated runtime fixtures under `Tests/BridgeJSRuntimeTests/Generated/` (via `BridgeJSTool generate`). - Verified runtime: `make unittest SWIFT_SDK_ID=DEVELOPMENT-SNAPSHOT+MAIN-wasm32-unknown-wasip1-threads` (passes).
