[BUG] The `@` file picker in Claude Code TUI does not respect `.claudeignore` patterns. Files from `.next/` directories appear in the fuzzy search results even when explicitly ignored.

What's Wrong?

The @ file picker in Claude Code TUI does not respect .claudeignore patterns. Files from .next/ directories appear in the fuzzy search results even when explicitly ignored.

Expected Behavior

Files inside .next/ should not appear in the @ file picker results.

Actual Behavior

.next/ files appear in the fuzzy search results:

• ./.next/types/app/(landing)/page.ts
• ./.next/types/app/(landing)/layout.ts
• ./.next/server/app/(landing)/page/react-loadable-manifest.json
• ./.next/server/app/(landing)/page/build-manifest.json
• etc.

Environment

• Claude Code version: v2.1.25
• OS: macOS (Darwin 25.3.0)
• Terminal: Ghostty

Notes

• The .next/ directory is also in .gitignore
• respectGitignore should be true by default
• The .claudeignore file is correctly placed in the working directory where claude is invoked

)"

What Should Happen?

The fuzzy search when doing '@/ file name' is broken. the .next files structures absorb all the list of the fuzzy search.

Steps to Reproduce

Steps to Reproduce

1. Create a Next.js project with a .next build directory
2. Create a .claudeignore file in the project root with:

``
.next
.next/**
``

1. Run claude from the project directory
2. Type @ followed by a search term that would match files in .next/ (e.g., @landing)
