[Bug] Keyboard input 'n' intercepted in agent creation text fields

Bug Description
When creating a new agent using manual configuration, the 'n' key is being intercepted during text input fields (agent name and system prompt). Instead of inserting the character 'n', Claude Code treats it as an Esc key press and navigates back one step.

Steps to Reproduce:

• Run /agents command
• Select "Create new agent"
• Choose manual configuration (Project or Personal)
• Begin entering an agent name or system prompt
• Press the 'n' key
• Observe Claude Code navigates back instead of inserting 'n'

Expected Behavior:

• The 'n' character should be inserted into the text field like any other letter.

Actual Behavior:

• The 'n' key triggers a back/escape action, preventing users from entering any agent names or system prompts containing the letter 'n'.

Impact:

• Users cannot create agents with names containing 'n' (e.g., "Translation Agent", "Python Helper").
