fix: worktree list columns misaligned when name/branch exceeds fixed width

[notdp]

Description

The wt list output columns become misaligned when worktree names or branch names exceed the fixed column widths.

Example

📁 my_project
   └─ ~/Developer/work/my_project
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  ▶ main          main               e6e738f   my_project
  • feishu-notification feature/feishu-notification e6e738f   my_project.feishu-notification

Root Cause

In bin/messages.sh, the list_global_worktree_entry message uses fixed-width printf format:

printf '  %s %-13s %-18s %-8s  %s' "$marker" "$name" "$branch" "$hash" "$path"

• Column 2 (name): %-13s - but "feishu-notification" is 18 chars
• Column 3 (branch): %-18s - but "feature/feishu-notification" is 27 chars

Affected Lines

• bin/messages.sh:647 (English)
• bin/messages.sh:1488 (Chinese)

Possible Solutions

1. Increase fixed widths - Simple but may still break with very long names
2. Dynamic column sizing - Calculate max width per column before printing
3. Truncate with ellipsis - Keep fixed width but truncate long values
