- Added early initialization of `ErrorHandler` in `main.cc` for robust error handling.
- Modified `ErrorHandler` to create the log file immediately, ensuring its presence in the state directory.
- Simplified conditional checks for log file operations and updated timestamp handling to use `system_clock`.
- Added a comprehensive error propagation standardization report detailing dominant patterns, inconsistencies, and recommended remediations (`docs/audits/error-propagation-standardization.md`).
- Integrated `ErrorHandler` into key components, including `main.cc` for robust exception reporting, and added centralized logging to a user state path.
- Introduced EINTR-safe syscall wrappers (`SyscallWrappers.h`, `.cc`) to improve resilience of file and metadata operations.
- Enhanced `DEVELOPER_GUIDE.md` with an error handling conventions section, covering pattern guidelines and best practices.
- Identified gaps in `PieceTable` and internal helpers; deferred fixes with detailed recommendations for improved memory allocation error reporting.
