Greptile Summary

This PR improves error handling and user feedback in the ClapConfigFile procedural macro by replacing silent error handling with explicit warnings. The changes focus on two critical areas of configuration parsing:

1. Current directory access during config file discovery: Previously, if std::env::current_dir() failed, the code would silently skip config file discovery using the ok()? pattern. Now it explicitly matches on the result and prints a clear warning message before falling back to skipping discovery.

2. Configuration building and deserialization: The original code used unwrap_or_else to silently fall back to default configurations when building or deserializing config data failed. The new implementation uses explicit match statements to catch these failures and print detailed warning messages, including the actual config data state when deserialization fails.

These changes maintain the same graceful fallback behavior (the macro still generates working code even when config loading fails) but significantly improve the developer experience by providing clear feedback about configuration issues. This is particularly valuable for a procedural macro that generates CLI and config parsing code, where users need to understand why their configuration files might not be loading correctly. The warnings include specific error context and guidance about what's happening ("Config file discovery will be skipped", "Continuing with default configuration"), making debugging much more straightforward.

Confidence score: 4/5

• This PR is safe to merge with minimal risk as it only improves error messaging without changing core functionality
• Score reflects that the changes are purely additive improvements to user experience without altering the underlying behavior
• No files require special attention as the changes are straightforward error handling improvements
