fix(vscode): send schema-valid permission responses

[chioarub]

Summary

• Fix VS Code chat permission approvals so Allow and Allow for session resolve tool prompts instead of looping.
• Send schema-valid can_use_tool control responses with behavior, updatedInput, and session updatedPermissions when applicable.
• Run the extension package test script with Bun's recursive src discovery.

Issue

Fixes #1034

What Changed

• Added permissionResponse.js helper to build SDK permission results.
• Store pending control request input and suggestions by request_id in ChatController.
• Updated sendPermissionResponse to emit correct allow/deny payloads.
• Updated the VS Code extension test script to run the full extension test set under Bun.

Validation

• cd vscode-extension/openclaude-vscode && bun test src/chat/permissionResponse.test.js — 3 pass, 0 fail
• cd vscode-extension/openclaude-vscode && bun run test — 42 pass, 0 fail
• cd vscode-extension/openclaude-vscode && bun run lint
• git diff --check

Risk

• Low — localized VS Code host protocol fix; deny path now uses explicit behavior: 'deny' instead of control error subtype.
