NapCat file messages have file_id in data["file_id"], not data["file"].
data["file"] is the filename, causing get_file API to return empty.
Also pass url field to downloadFile for URL-direct fallback.
go_invoke_tool does json.Marshal(r) on handler results. When r is a string,
the raw JSON gets wrapped in quotes and escapes, causing the core's
json.Unmarshal into map[string]interface{} to fail (displayed as map[]).
Changed return type to json.RawMessage (implements json.Marshaler, outputs
raw bytes inline). Added rawString() helper for callers that need the
string representation.
- resolveBuild: use plugin.dylib for darwin (was plugin.so)
- --bundle flag: build linux/amd64 + darwin/amd64 + windows/amd64,
package all binaries into a single .hmap with platforms field
- writePluginJSON: accept platforms []string for bundle manifest
- add createBundleHmap for zip entries with custom names
- add PlgConfig.IsLua() helper
- detectSDKInfo now returns SDK version from meta/meta.go
- Generated plugin go.mod uses real version (v0.7.1) instead of v0.0.0
- Tag v0.7.1 created for SDK version management
- Add 'plugindev sdk' subcommand with list/install/use/path/current/latest
- Replace runtime.Caller(0) path detection with managed SDK store
- SDK stored at ~/.homeagent/plugindev/sdk/<version>/
- Active version tracked via current file
- Lazy initialization to avoid blocking other subcommands
- handleChannelOutput: read payload/meta/type instead of content JSON
- Route by type: text/voice/image/file
- buildOutputHelp: show new parameter format
- Remove fixJSON (no longer needed without JSON-within-JSON)
