feat : Add autocomplete suggestions for partially typed commands

[surajpathakcs]

feature: Partially visible commands on typing available commands

Issue Description:
The objective is to create an auto-completion feature where, as the user types a command, partially matching commands become visible. This feature will help users see the available commands based on their input, even if they haven't typed the full command yet.

Requirements:
Partial Matching: When a user types part of a command, the system should display commands that start with the entered text.
Auto-completion Suggestions: Suggestions should dynamically update as the user types.
Highlight Partial Matches: It should be clear which part of the suggestion matches the user's input (e.g., via bold or color).
Navigation for Suggestions: Allow users to navigate the suggestion list using arrow keys (up and down) and select the appropriate command.
