Intermittent command-send failure with @tarquinen/opencode-dcp. UI shows: 'Befehl konnte nicht gesendet werden' and 'Error: DCP_CONTEXT_HANDLED' with stack trace to ....cache\opencode\node_modules@tarquinen\opencode-dcp\dist\lib\hooks.js:113:27. Environment: OpenCode 1.2.1, plugin @tarquinen/opencode-dcp@2.1.3, Windows. Expected: command should send successfully or internal sentinel errors should not surface as fatal user-facing errors. Observed: request fails before send path completes. Possibly related: #304 and #353.
