[FEATURE] meaningful tab-titles in Windows Terminal to aid crash-recovery

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

• Claude Code on Windows is crashing frequently due to contentious writes to ~/.claude/settings.json.
• Windows Terminal tabs for multiple Claude Codes sessions are titled "Claude Code"
• When restarted, Windows Terminal does not start over with same tabs - they have to be reopened manually

Proposed Solution

• Displaying names of repos / directories in tab-titles instead of "Claude Code"
• User could then quickly note down which tabs open before restarting Windows Terminal

Alternative Solutions

Not needed for macOS terminal which both displays directory-names AND restarts with former tabs open at correct cwd/pwd.

Priority

High - Significant impact on productivity
