Show end of working directory path instead of beginning in welcome banner

The welcome banner truncates the working directory path from the right, showing the beginning of the path:

~\OneDrive\Documents\David\Personal\Artificial In...

For users with deeply nested project directories (common on Windows with OneDrive), the truncated portion is the only meaningful part — the actual project name. The visible portion (OneDrive, Documents, Personal) provides no useful context.

Requested behavior

Truncate from the left instead, showing the end of the path:

...Artificial Intelligence\AI Builds\Claude Code Reference Guide

Or use a middle-truncation approach:

~\...\AI Builds\Claude Code Reference Guide

Why this matters

• The project name is the most useful information at a glance
• Parent directories like OneDrive\Documents are rarely needed
• Even on a fully expanded 32-inch monitor, the path still truncates before reaching the project folder
• Other tools (VS Code breadcrumbs, terminal prompts like Starship) solve this by truncating from the left or middle

Environment

• Claude Code v2.1.88
• Windows 11 Pro
• Deeply nested OneDrive path
