🎨 Palette: Add trailing space to generic input prompts

[abhimehro]

💡 What: Added logic to automatically append a trailing space to prompt strings in get_validated_input and get_password if one is missing.

🎯 Why: When prompting users for input via generic wrappers, if the prompt string lacks a trailing space, the user's typed input visually collides with the prompt text. This creates a cluttered and confusing user experience.

♿ Accessibility: Improves readability for visually impaired users and screen readers by ensuring distinct separation between the system's prompt and the user's input.

(Also recorded critical learnings regarding generic input cancellation safety in .Jules/palette.md).

Pull request overview

This PR improves CLI prompt readability by ensuring generic input wrappers always separate the prompt text from the user’s typed input with a trailing space, preventing visual “prompt/input collision” in interactive runs.

Changes:

• Auto-append a trailing space to prompt in get_validated_input() when missing.
• Auto-append a trailing space to prompt in get_password() when missing.
• Document prompt-collision and generic-input cancellation safety learnings in .Jules/palette.md.

File	Description
main.py	Ensures input()/getpass() prompts rendered via shared wrappers end with a trailing space for clearer UX.
.Jules/palette.md	Records UX and safety learnings about prompt formatting and cancellation handling scope.

Code Review

This pull request introduces automatic trailing space appending to input prompts in main.py and updates the .Jules/palette.md documentation with learnings on prompt collision and cancellation safety. Feedback recommends using .isspace() for a more robust whitespace check in the prompt handling logic to avoid redundant spacing and suggests consolidating the new documentation entries to avoid redundancy with existing content.

[gemini-code-assist]

Using .endswith(" ") only checks for a literal trailing space. If the prompt ends with other whitespace characters like a newline (\n) or a tab (\t), this logic will append an unnecessary extra space. Using .isspace() on the last character is more robust as it ensures any form of whitespace separation is respected, preventing redundant spaces in those cases.

Suggested change

	if not prompt.endswith(" "):
	prompt += " "
	if prompt and not prompt[-1].isspace():
	prompt += " "

This new entry is largely redundant with the existing learning and action recorded on lines 33-34. While it specifies "generic wrappers", the core issue (visual collision) and the solution (trailing space) are already covered. Consider consolidating these entries to keep the palette file concise and maintainable.
