Backslash-dot sequence in terminal output drops the backslash

Description

When Claude Code's terminal output contains a Windows path with \. (backslash followed by a dot), the backslash is dropped during rendering. The path displays incorrectly.

Steps to reproduce

1. Run /insights (or any command that outputs a Windows path containing \.)
2. The output includes a file:// URL like: file://C:\Users\username\.claude\usage-data\report.html
3. The rendered terminal output shows: file://C:\Users\username.claude\usage-data\report.html — the backslash before .claude is missing

Expected behavior

The full path should render as-is: C:\Users\username\.claude\usage-data\report.html

Actual behavior

\. is interpreted as an escape sequence, consuming the backslash: C:\Users\username.claude\usage-data\report.html

Environment

• Windows 10 Pro 10.0.19045
• Claude Code terminal (not a browser — this is the CLI output renderer)
