fix: Code review fixes for multiple Python files

Browse source 
Fixed the following issues:

1. gitstatus.py:
   - Fixed broad IOError exception handling to catch specific OSError/FileNotFoundError
   - Fixed unused variable warning by using _ for ignored stderr

2. proxy.py:
   - Fixed os.path.expandvars usage that doesn't expand ~, changed to os.path.expanduser
   - Fixed check_output call that was incorrectly passing a file path instead of command list
   - Fixed missing space in env variable assignment for aliases

3. update_emoji.py:
   - Fixed file handle leaks by using with statements for file operations
   - Removed unnecessary .keys() call in dict iteration

4. cheatsheet.py:
   - Fixed parse() function to handle lines without '=' character
   - Fixed inefficient list comprehension using any() instead
   - Fixed shadowing of built-in 'cheatsheet' function name

5. ssh-agent.py:
   - Modernized string formatting from .format() to f-string

6. ssh-proxy.py:
   - Fixed next() call without default value that crashes when no proxy env vars set
   - Fixed missing exit code propagation from subprocess.call
