[BUG] File paths with parentheses (Next.js route groups) break terminal clickability in diff/edit output

Description

When working with Next.js App Router projects that use route groups (e.g., (dashboard)), file paths displayed in Claude Code's diff/edit output break terminal link detection. The parentheses cause terminals to truncate the clickable path at the ( character.

Steps to Reproduce

1. Have a Next.js project with route groups like src/app/(dashboard)/
2. Edit any file inside the route group
3. Observe the file path shown in the diff output

Expected Behavior

The full file path should be clickable in the terminal, e.g.:

frontend/apps/dashboard/src/app/(dashboard)/invoices/new/invoice-create-form.tsx

Actual Behavior

The terminal interprets ( as the end of the clickable region. The path breaks visually and functionally — clicking opens nothing or only the partial path up to (dashboard.

Environment

• macOS (Darwin 25.3.0)
• Terminal: standard macOS terminal / iTerm2
• Next.js App Router with (dashboard) route group

Suggested Fix

Escape or encode parentheses in file paths when rendering output, or use OSC 8 hyperlinks (ref #13008) with properly escaped file:// URIs where ( → %28 and ) → %29.
