Drop Hunyuan (Tencent TC3-HMAC) — high effort and not testable by the maintainer: delete HunyuanAdapter + TencentCloud3Signer (+tests), unwire from AssetGenProviders, SecureKeyStoreConstants, the GUI provider list, and Python/CLI/README/manual-verify docs. Refresh model defaults to current (2026) SOTA, verified against provider docs: - fal: fal-ai/flux/dev -> fal-ai/flux-2 (FLUX.2 dev; cheaper and higher quality) - Tripo: v2.5-20250123 -> v3.1-20260211 (current recommended model) - Meshy: drop deprecated art_style (errors on Meshy-6); pin ai_model=meshy-6 - OpenRouter: gemini-2.5-flash-image-preview (delisted) -> gemini-2.5-flash-image Fix two tests that asserted the now-implemented 'meshy' provider throws (repointed to the now-removed 'hunyuan'). They were silently wrong: the headless --full runs never executed EditMode tests (Unity -quit exits before -runTests; compile-only). A real -runTests run now passes 62/62 AssetGen EditMode tests; Python suite 1299 passed. Claude-Session: https://claude.ai/code/session_01Tjpb5gYgUe2AUJuRdXr7Lv
