[FEATURE] Add option to show file reads inline instead of collapsed

• [x] This is a single feature request (not multiple features)

Problem Statement

Previously Claude Code showed which files it was reading inline. Now this is collapsed into "read X files (ctrl+o to expand)".

I cannot see what Claude is reading without pressing Ctrl+O every time. This reduces transparency and makes it harder to follow Claude's reasoning.

Proposed Solution

{
"ui": {
"collapseFileReads": false
}
}

Alternative Solutions

Currently I press Ctrl+O every time to expand. This breaks workflow and is tedious.

Priority

Medium - Would be very helpful

Feature Category

CLI commands and flags

Use Case Example

1. I ask Claude to investigate a bug
2. Claude reads files but I only see "read 5 files"
3. I don't know which files without pressing Ctrl+O
4. Hard to follow Claude's reasoning in real-time
5. Previously file paths were shown inline

Additional Context

This was introduced in recent versions. Previous behavior showed file paths inline which was more transparent.
