feat(lua plugin): align Lua plugin bridge with C ABI surface, accept table args in sdk.memory.recall

- Lua 桥接层补齐 register_def/no_memory/cleaner/own_tools/output+input channels/register_api/set_auto_restart 等 v0.8.0 能力，与 C ABI 插件面一致
- sdk.memory.recall 兼容表参数（多 key 批量 recall），修复 Lua 插件传表报 bad argument
- 新增 TestLuaAlignedAPIs 覆盖对齐后的 API 面（含 recall 数组回归断言）
- sdk.lua 同步子表 mock（memory/doc/knowledge/text_memory/llm/social/settings）
- 更新 PLUGIN_DEV.md 中英文示例插件参考表
