🤖 Generated by Copilot at e4fef90

This pull request improves the file filtering and logging functionality in the wandb/sdk/lib and wandb/sdk modules, and adds unit tests for the filenames.py module. It allows users to customize the file inclusion and exclusion criteria for logging source code to the W&B dashboard, and makes the file filtering logic more robust and flexible.

More specifically, this addresses an issue that prevents log_code from behaving as expected when the absolute path to the root directory contains wandb or .wandb. This PR...

1. expands log_code to allow callers to pass either 1- or 2-parameter callables for include_fn and/or exclude_fn, where the 1st argument is the absolute file path, and the 2nd argument is the absolute root path
2. reimplements the default exclude_fn to exclude only <root>/.wandb/* and <root>/wandb/* as originally intended, and NOT all paths that contain .wandb or wandb anywhere.
