refactor: simplify logging in Android bootstrap script

The `LogFile` class and related code for handling stdout/stderr logging were removed and replaced with direct printing to `sys.stderr`. This change simplifies the logging mechanism and ensures consistent output behavior. The removed code was redundant and added unnecessary complexity. No breaking changes are introduced, as the logging output remains functionally the same.

refactor: Remove redundant logging and simplify pip install command

- Remove redundant 'info' logging in bootstrap.py for found directories to reduce noise in logs.
- Simplify pip install command in build.py by removing '--no-deps' flag, allowing dependencies to be installed as needed.
```

refactor: comment out private.tar creation in build.py

The creation of private.tar in the build process is temporarily disabled by commenting out the relevant code. This change is made to streamline the build process and avoid unnecessary steps, as private.tar is not currently required. No breaking changes are introduced, and the functionality can be restored by uncommenting the code if needed in the future.
