/insights: file:// URL broken on Windows — backslash before .claude dropped, link not clickable

Bug

The /insights command generates a report URL that doesn't work on Windows:

file://C:\Users\akhil\.claude\usage-data\report.html

Two issues:

1. Backslash before .claude gets dropped in rendering — the path displays as C:\akhil.claude instead of C:\akhil\.claude, because the \. sequence is interpreted as an escape or path separator issue in the markdown/terminal rendering.

1. Link is not clickable — file:// URLs with Windows backslash paths don't work as clickable links in terminals. On Windows, the URL should use forward slashes: file:///C:/Users/akhil/.claude/usage-data/report.html

Expected behavior

The report URL should be clickable and resolve to the correct path on Windows.

Suggested fix

On Windows, convert backslashes to forward slashes in the file:// URL and use the triple-slash file:/// convention:

file:///C:/Users/akhil/.claude/usage-data/report.html
