Fix path expansion for Slack cookies on macOS

Problem: Cookie file path contains unexpanded ~ tilde, causing 'unable to open database file' error when trying to access Slack cookies. String-based path operations don't handle ~ expansion.

Fix: Use Path.home() from pathlib stdlib (https://docs.python.org/3/library/pathlib.html#pathlib.Path.home) which properly expands to the user's home directory.
