 - Updated frontend session polling to use the new no-touch validity path and avoid stale query cache via forced refresh behavior.
 - Added frontend session end command to explicitly release the linked device on session teardown/ejection.
 - Updated admin link revoke flow to release the linked device after revocation so revoked sessions do not leave devices stuck `inUse`.

+### 15 — Orchestrator App Launch Robustness
+
+- Updated Android launch flow in orchestrator to resolve launcher activity via `cmd package resolve-activity` and launch with `am start -n <activity>`.
+- Kept `monkey` as fallback only when launcher activity cannot be resolved, reducing redroid/device-specific `monkey` failures during session prepare.
