Adds scripts/abi-ffi-gate.py (fails on a declared ABI C function with no Zig export, a mismatched result-code map, or an unrendered template token) and a .github/workflows/abi-ffi-gate.yml that runs it plus a Zig 0.14.0 build/test of the FFI. The Idris2 ABI is the source of truth. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019xMKB3T4Vo5FYC7Czx3JSH

ABI↔FFI conformance gate
Adds a CI gate enforcing that the Zig FFI (
src/interface/ffi) conforms to the Idris2 ABI (src/interface/abi— the source of truth):scripts/abi-ffi-gate.py— fails (exit 1) if a declared%foreign "C:<name>"symbol (across all ABI.idrfiles) has noexport fnin the Zig, if the ZigResult = enum(c_int)and IdrisresultToIntdisagree on names or values, or if an unrendered{{...}}template token remains. No toolchain required..github/workflows/abi-ffi-gate.yml— runs the gate, plus builds + tests the FFI under the pinned Zig 0.14.0.Verified non-vacuous (it fails on a dropped export, a wrong result-code value, and a leftover template token) and green on this repo. This is the gate that catches the FFI drift class fixed across the family this session (unrendered templates, missing domain functions, symbol-name drift, result-code semantic mismatches).
