Pull Request Overview
This PR implements enhanced error handling for standard (std) environments in AimDB, adding rich error capabilities while maintaining full backward compatibility with embedded/no_std targets. The implementation adds error chaining, standard library integration, and anyhow compatibility for improved error handling in edge and cloud deployments.
- Enhanced error handling with context chaining via
with_context()method for building detailed error context chains - Standard library integration with automatic conversions from
std::io::Errorandserde_json::Error - Anyhow compatibility through
into_anyhow()method for seamless application boundary integration

The array literal [...] was changed to vec![...] but the variable is still named errors which doesn't reflect that it's now a mutable vector. Consider renaming to mut errors or keeping it as an array if mutability isn't needed for the basic error variants.

This function performs two separate insert_str operations at position 0, which is inefficient as each insertion shifts all existing characters. Consider using a single allocation approach like *existing = format!(\"{}: {}\", new_context, existing); or building the string in the correct order to avoid multiple string shifts.

Similar to the previous helper function, this performs two insert_str operations at position 0, causing unnecessary string copying. Consider using *existing = format!(\"{}: {}\", new_context, existing); for better performance.
