refactor: remove dead code and rename V2 files (#541)

* refactor: remove V1 dead code and rename V2 files

- Delete extractor/ package (V1 Extractor interface and registry)
- Delete browserdata/ package (V1 orchestrator, outputter, 9 sub-packages)
- Delete V1 browser implementations (chromium.go, chromium_{platform}.go, firefox.go)
- Delete types/types.go (V1 DataType enum) and utils/byteutil/
- Remove gocsv and go-sqlmock dependencies, demote x/text to indirect
- Upgrade keychainbreaker v0.1.0 → v0.2.5
- Rename chromium_new.go → chromium.go, firefox_new.go → firefox.go

* refactor: remove unused V1 utility functions

Remove functions no longer called by V2 code:
- fileutil: IsDirExists, CopyDir, BrowserName, ReadFile, CopyFile,
  Filename, ParentDir, ParentBaseDir, BaseDir
- typeutil: Keys, IntToBool
