fix(claude): classify stop diagnostics as interrupted

[D3OXY]

Summary

• correlate Claude SDK interrupt requests with the active provider turn
• treat a diagnostic-only error_during_execution result as interrupted only when it follows an explicit interrupt for that turn
• keep unrelated Claude execution diagnostics classified as failures

Claude can return this after stopping during tool use:

[ede_diagnostic] result_type=user last_content_type=n/a stop_reason=tool_use

Without explicit correlation, the adapter classified it as a failed turn and surfaced the internal diagnostic as a runtime error.

Verification

• vp test run apps/server/src/provider/Layers/ClaudeAdapter.test.ts (63 passed)
• vp fmt --check apps/server/src/provider/Layers/ClaudeAdapter.ts apps/server/src/provider/Layers/ClaudeAdapter.test.ts
• vp lint apps/server/src/provider/Layers/ClaudeAdapter.ts apps/server/src/provider/Layers/ClaudeAdapter.test.ts
• vp run --filter t3 typecheck

Note

Classify diagnostic-only Claude stop results as interrupted when an explicit interrupt was requested

• Adds interruptRequestedTurnId to ClaudeSessionContext to track which turn had an explicit interrupt requested, set in interruptTurn and cleared after result handling.
• Introduces isClaudeExecutionDiagnosticOnlyResult to detect error_during_execution results with a single [ede_diagnostic] error string.
• isInterruptedResult and turnStatusFromResult now accept an explicitInterruptRequested flag; diagnostic-only results are classified as interrupted when this flag is true.
• If the interrupt call fails, the stored turn ID is cleared to avoid misclassifying future results.
