- **File System API Expansion & Hardening**: Implemented native POSIX bindings for `mkdir`, `rm`, `rm_dir`, `touch`, `ls`, `is_dir`, `is_file`, `file_size`, `mv`, and `copy`. - **Zero-Copy Architecture**: The `copy` routine now utilizes the Linux `sendfile` syscall, piping bytes entirely within kernel space for maximum throughput, bypassing user-space memory allocation. - **OS-Level Error Handling**: Deprecated legacy `flint_panic` in I/O operations. `read_file`, `write_file`, and all new FS functions now return a boxed `FlintValue`, bubbling up genuine OS `errno` strings to the Flint `catch` block. - **Test Infrastructure Revamp**: Replaced shallow directory iteration with Zig's recursive `Walker`. Tests are now strictly segmented by domain (io, http, arrays, strings, etc.), tracking relative execution paths and enforcing strict teardown hygiene. All 27/27 test suites passing. The foundation for DevOps scripting is now solidified.
