[BUG] Super minor capitalisation discrepancy in `help` output

Environment

• Platform (select one):
• [ ] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [x] Other: <!-- specify --> Ubuntu desktop
• Claude CLI version: <!-- output of claude --version --> 0.2.105 (Claude Code)
• Operating System: <!-- e.g. macOS 14.3, Windows 11, Ubuntu 22.04 --> Ubuntu 25.04
• Terminal: <!-- e.g. iTerm2, Terminal App --> Gnome Terminal

Bug Description

The "display help for command" in -h, --help or claude help appears as "display help for command" and not "Display help for command". All other options have a Capitalised first letter.

Steps to Reproduce

$ claude --help
...
  -c, --continue                  Continue the most recent conversation
  -r, --resume [sessionId]        Resume a conversation - provide a session ID or interactively select a conversation to resume
  -h, --help                      display help for command
...

or

$ claude mcp help
....
  reset-project-choices                          Reset all approved and rejected project-scoped (.mcp.json) servers within this project
  help [command]                                 display help for command
...

Expected Behavior

Capital 'D'

Actual Behavior

Lower case d

Additional Context

This is beyond minor but...also maybe trivial to fix :)
