Previously the wrapper silently ignored json.Unmarshal errors and returned
nil, causing tools returning raw JSON strings (via C ABI bridge's
json.Marshal) to appear as empty map[] to the agent.
- SDK: RegisterStage(stage, handler, scope...) with StageScopeGlobal/StageScopeOwnTools
- Delete RegisterStageOwnTools, migrate cmd and qq plugins
- Internal SDK: add StageScope alias
- Docs: update all zh/en docs for C ABI buildmode and stage scope
- C ABI: fix nil errorOut in Handle.Start/Handle.Stop (SIGSEGV fix)
- C ABI header: add dispatch IDs 26-45 for Settings/Doc/Knowledge/LLM/Social/TextMemory
- Replace invokeTool/invokeOutput/invokeStage callbacks with standalone
functions pluginInvokeTool/pluginInvokeOutput/pluginInvokeStage
- Case 1: sync tool invocation (not async - LLM needs return value)
- Case 2/3: use pluginID + pluginMap lookup instead of closures
- Store ps.api in pluginState for direct C function calls
- go_core_dispatch case 1: tool handler now calls back to plugin via invokeTool
- go_core_dispatch case 2: stage handler sends full StageContext (11 fields)
- New dispatch methods 26-31: Settings.GetCore/SetCore/ListCore/GetPlugin/SetPlugin/ListPlugin
- Remove dlclose (plugin goroutines may still be running after Stop)
- invokeTool/invokeOutput/invokeStage callbacks with proper error handling
- Fix n2 unused variable
- go_core_dispatch case 2/3 no longer stub - real callbacks to plugin
- pluginState.invokeOutput/invokeStage call plugin's go_invoke_output/stage
- OutputChannel registration via IOManager.RegisterDevice
- Stage handler registration via PluginSDK.RegisterStage
- internal/plugin/cabi/: dlopen + dlsym for plugin_init
- create_core_api(): C struct with dispatch_bridge→go_core_dispatch
- go_core_dispatch routes all 25 SDK methods (RegisterTool, MemoryAPI, etc.)
- dynamic.go: cabiPlugin uses CreateCoreAPI(sdk)→Start(corePtr)
- Each plugin gets a unique ID stored in CoreAPI.ctx
- C functions moved to loader.c to avoid cgo duplicate symbol issues
- New internal/plugin/cabi/ package: dlopen + dlsym loader
- plugindev: generates z_entry.c + z_bridge_gen.go for c-shared builds
- plugindev: replaces -buildmode=plugin with -buildmode=c-shared
- Go bridge uses mock SDK during Start(), core discovers registrations
- PluginAPI: init/start/stop + invoke_tool/stage/output + get_tool_defs/stages/channels
- ha_dispatch: single C function handles all plugin→core calls via method ID
- tryLoadSO: tries C ABI first, falls back to Go plugin.Open
- All example plugins updated (main.go removed, plg.json targets updated)
