v0.6.0

Added

• timber.accel — TimberAccelerate merged into core (previously a separate timber-accelerate package, now ships with every pip install timber-compiler install):
  • SIMD codegen — AVX2Emitter, AVX512Emitter, NEONEmitter, SVEEmitter, RVVEmitter; injects vectorised timber_infer_simd() path into generated C; delegates timber_infer_single and timber_infer to SIMD variant at link time
  • GPU codegen — CUDA, Metal, OpenCL emitters
  • FPGA HLS — Xilinx Vitis HLS, Intel FPGA SDK emitters
  • Embedded — Cortex-M, ESP32, STM32 emitters (no-heap, static buffers, cross-compile prefix support)
  • WCET analysis — analyze_wcet(ir, arch, clock_mhz, safety_margin) for Cortex-M4/M7, x86_64, AArch64, RISC-V64; per-stage breakdown with advisory disclaimer
  • Safety transforms — deterministic_pass and constant_time_pass IR transforms
  • Certification reports — DO-178C, ISO 26262, IEC 62304 compliance report generation
  • Supply chain — Ed25519 artifact signing/verification, AES-256-GCM encryption/decryption, TPM integration hooks
  • Deployment — air-gapped bundle creator, C++ gRPC server generator, ROS 2 node generator, PX4 autopilot module generator, sensor preprocessing (radar, RF, telemetry)
  • 18 target profiles (TOML) bundled at timber/accel/targets/: AVX2, AVX512, NEON, SVE, RVV, CUDA SM75/SM86, Metal Apple M1, OpenCL generic, Cortex-M4/M7/ESP32/STM32, HLS Xilinx/Intel
  • 3 compliance profiles (TOML) bundled at timber/accel/compliance_profiles/: DO-178C, ISO 26262, IEC 62304
  • timber-accel CLI — 9 commands: compile, wcet, certify, sign, verify, encrypt, decrypt, bundle, serve-native
