feat(amazonq): inline unit test generation

[Will-ShaoHua]

Problem

UTG is not implemented in Flare and also science team proposed improvement based on the existing UTG living in VSCode/Jetbrains.

Solution

unitTestIntentDetection.ts is the logic to check provided file and its content is a test file or src file.
focalFileResolution.ts is the logic to resolve the focal file (i.e. src file of the provided test file)

unitTestIntentDetection is complete
focalFileIdentity is WIP

When isUtg is true but inferFocalFile fails to identify a focal file, should we fall back to using BM25 to retrieve supplemental context? Currently, the logic seems to return an empty result in this case.

will follow up

should use either \r?\n or os.EOL

[Will-ShaoHua]

nm these are not used at this point. Will consider removing them when we're sure they are 100% not needed anymore
