fix(intellij): enforce results limit for glob search

[xxsLuna]

Summary

This PR fixes a bug where the maxResults parameter was not correctly passed from the Core engine to the IntelliJ extension during glob searches, causing context overflow in large repositories.

Key Changes

1. Core Protocol: Updated core/protocol/messenger/messageIde.ts to include the maxResults parameter in the getFileResults request payload. Previously, this parameter was missing, causing the IDE implementation to receive undefined.
2. IntelliJ Extension: Updated IntelliJIde.kt to handle the maxResults parameter. It now filters out blank lines and uses .take(maxResults) to ensure the returned file list complies with the requested limit.

Impact

• Standardizes glob search behavior between VS Code and IntelliJ.
• Prevents context overflow issues when using @codebase or broad glob patterns in large projects.

Verification

• Verified on a repository with 10k+ files (integrated the fix into a micube-final branch).
• Confirmed that results are now capped at 100 files and the "Truncation warning" is visible in the chat interface.

Closes #11999
