feat(firmware): iec_runtime_fault glue + strucpp v0.5.8

[thiagoralves]

Adopts strucpp v0.5.8 (target-aware runtime fault path).

• arduino_runtime_glue.cpp: weak default strucpp::iec_runtime_fault (halt) for MCU targets compiled -fno-exceptions. VPP HALs may override (P1AM blinks its LED).
• binary-versions.json: strucpp v0.5.7 → v0.5.8.

No -fexceptions change here — the editor never hardcoded it (it came from VPP cxx_flags, removed in openplc-packages). Matching openplc-web PR opened with byte-identical firmware.

• Autonomy-Logic/openplc-editor#875: Directly analogous change — bumps the same strucpp.version field in binary-versions.json (from v0.5.6 to v0.5.7).
• Autonomy-Logic/openplc-editor#834: Also only bumps the strucpp version in binary-versions.json, modifying the same exported binary metadata field.
• Autonomy-Logic/openplc-editor#786: Same pattern — bumps the pinned strucpp version in binary-versions.json.

Poem

🐇 A tiny hop, a single line,
The strucpp jumps from seven to eight so fine,
v0.5.8 now takes the stage,
A fresh new version on the page,
This bunny approves — change is divine! 🌟
