feat(widgets): add Claude account email widget

[FA387]

Summary

• Adds a new Claude Account Email widget in the Session category
• Displays the currently authenticated user's email directly in the ccstatusline status bar
• Resolves email by reading git config user.email first, then falls back to common environment variables (GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, EMAIL, USER_EMAIL)
• Returns null gracefully if no email source is found (widget is hidden)
• Supports raw value mode and color customization

Widget details

Property	Value
Display name	Claude Account Email
Category	Session
Default color	blue
Preview value	you@example.com

Why this is useful

When using Claude Code with multiple accounts (e.g. via ccswitch), it's helpful to see at a glance which account/email is active in the status line — no need to run git config user.email separately.

Test plan

• Add the widget via the TUI (bun run start) under the Session category
• Verify it shows your git config email in the status bar
• Test fallback: unset git config user.email, set EMAIL env var instead
• Verify preview shows you@example.com in the TUI editor

@FA387 Can you explain how the configured git email relates to the authenticated Claude account? To pull the Claude account email you'd need to look in ~/.claude.json. I'd be happy to add this as a Git Email widget, but it doesn't seem related at all to the Claude account.

[FA387]

Good catch, thanks for the feedback! You're right — git email and Claude account email are completely unrelated.

I've updated the widget to read oauthAccount.emailAddress directly from ~/.claude.json (with CLAUDE_CONFIG_DIR support), which is the actual logged-in Claude account. No dependency on any external tool.

P.S.
I modify it with Claude Code for me to easily distinguish between my personal account and my work account with Teams.

I think it will help other people in the same situations

Best regards
FA
