rfc: force show/hide cursor option

[dwmkerr]

Context

Cursor rendering now respects terminal state automatically via terminal.modes.showCursor.

Potential Enhancement

If users need explicit control to force cursor on/off regardless of terminal state, we could add a parameter:

shell_screenshot({ session_id, showCursor?: 'auto' | 'show' | 'hide' })

• auto (default): respect terminal state
• show: always render cursor
• hide: never render cursor

Use Cases

• Force show cursor in TUI apps that hide it
• Force hide cursor in shell sessions for cleaner screenshots

Please comment if you have a use case for this.
