alternative-intelligence-cp/aria: v0.9.1 — Core Stdlib Ports

Core Stdlib Ports Ported 4 fundamental stdlib modules from direct FFI (extern func:) to aria-libc-backed implementations, and created 1 new pure-Aria module. Changes math.aria: 7 inline externs → extern "aria_libc_math" block (fmod, hypot, copysign, fma, isnan, isinf, isfinite) io.aria: 8 inline externs → extern "aria_libc_io" block (fopen, fclose, fread, fwrite, fgets, fputs, feof, fflush) mem.aria: 7 inline externs → extern "aria_libc_mem" block with 14 functions; complete type migration from wild int8* to int64 handles string.aria: 18 inline externs → 2 extern blocks + compiler builtins; complete split-handle redesign fmt.aria (NEW): Pure Aria string formatting — template placeholders, int/float/bool/hex formatting, padding, repeat Stats 40 inline extern func: declarations eliminated 73 test assertions, all passing (math:15, io:7, mem:8, string:27, fmt:16) 1 new stdlib module (fmt.aria) 3 new aria-libc string shim functions (byte_at, copy_to_buf, from_buf) Build cd build && cmake .. && make -j$(nproc) Full changelog: v0.9.0...v0.9.1
