[FEATURE] Add plugin setting to auto-accept edits in JetBrains IDE (without diff dialog)

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Add a single checkbox in Settings → Tools → Claude Code [Beta]:

☐ Auto-accept edits (skip in-IDE diff dialog when CLI is in acceptEdits or bypassPermissions mode)

When enabled, the plugin's openDiff MCP tool should:

1. Check the connected session's current permission mode via the existing CLI ↔ plugin SSE bridge
2. If mode is acceptEdits or bypassPermissions, apply the diff directly and skip the dialog
3. Otherwise, behave as today

This keeps the safety story intact (default mode still prompts), respects the user's explicit choice to enable acceptEdits, and matches the documented contract of those modes:

"acceptEdits mode lets Claude create and edit files in your working directory without prompting." — https://code.claude.com/docs/en/permission-modes

Alternative Solutions

The only workaround is to stop using the IDE integrated terminal and run claude in an external terminal (iTerm2 / Terminal.app). This bypasses the SSE bridge entirely. But it sacrifices @-file references, getDiagnostics, selection capture, and other IDE integration features — exactly the things the plugin exists to provide.

CLI commands and flags

Use Case Example

For users running Claude on a long multi-file task (refactor, migration, large feature implementation), clicking Apply 50+ times during a single session destroys the productivity case for acceptEdits mode and pushes users back to manual editing or to non-IDE-integrated CLI usage. The feature exists, the documentation promises it works, but the plugin silently overrides it.

Additional Context

Please reconsider this as a P1 plugin defect rather than a feature request.

Environment:

• Claude Code: 2.1.169
• JetBrains plugin: 0.1.14-beta
• IDE: Android Studio (also reproduced in IntelliJ, PyCharm, RubyMine per #37533)
• OS: macOS
