Registers dntof.sample_adapted with SLDataAPI:

• capabilities: sample.hello
• status: { "ok": true, "message": "sample online", "bumps": 0 }
• route hello: { "ok": true, "plugin": "dntof.sample_adapted" }

Build after SLDataAPI Release build, then copy DLL to LabAPI plugins/global.

Registered via PluginEndpointRegistry.TryRegisterActions (SLDataAPI with beta support; older builds are detected via MissingMethodException and the sample stays read-only):

Called through the control plane (HTTP POST /control/adapted/dntof.sample_adapted/echo, or WS call with the same path). Requirements:

1. beta_adapted_plugin_actions: true in SLDataAPI config.yml (otherwise 404, and actions is not listed in /plugins/adapted).
2. The API key needs an explicit grant — /control/adapted/ is never granted by admin duty or all_control_true. Use endpoints_override, e.g. "/control/adapted/dntof.sample_adapted/": true (one plugin) or "/control/adapted/": true.
3. Every call is a write: it is recorded in control_log (body redacted for secrets).

Handlers run on the Unity main thread with a 3 s timeout; throw AdaptedActionException(message, status) to return a 4xx.
