chore: Ignore generated files and directories

This commit updates the .gitignore file to exclude files and directories that are generated by the build system or are not meant to be tracked in the repository.

- : This directory contains components managed by the build system.
- : This is a binary file, likely a pre-compiled filesystem image.
