File and MCP resource search fails to match text hidden by truncation #7388

Description

Problem

When attaching files or MCP resources using @ in the TUI, long paths/URIs are truncated with "..." in the middle for display (e.g., src/components/f...ationService.ts). The fuzzy search runs against this truncated string, so typing text hidden by the ellipsis fails to find matches.
This affects:

Files - long file paths
MCP Resources - long resource names/URIs

Expected behavior

Fuzzy search should match against the full path/URI, not the truncated display string.

Resize your terminal window to be as small as possible while still being able to type in the input field
Have a file with a long path (e.g., src/components/files/FileValidationService.ts)
Type @ to open the autocomplete menu
Start typing part of the filename that gets hidden by truncation (e.g., "Validation")
The file doesn't appear in the results, even though it should match
