- 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
