Prepare 0.1.0: one dotenv grammar, path policy, redactor, and safer writes

- parseDotenv, validate, and every edit share the round-trip document parser
- Path policy helpers (isEnvFile, isSensitiveEnvFile, isEnvSitterPepperFile) used by envsitter-guard
- CLI file commands run through the library file operations
- EnvSitter#redactor() and the redact command replace secret-looking values in text
- Writes keep file permissions and go through symlinks; new files are 0600
- An existing pepper is never replaced; a new .envsitter/ gets a .gitignore
- set/add/copy into empty files write clean output
- Regexes with g/y flags no longer skip keys
- TypeScript 6, Node 22+ engines, prepack build, dist/test excluded from the package
