Feat : Add list formatting with auto-continuation to message composer

[not-meet]

Summary

Add smart Markdown list formatting of ordered and unordered list to the message composer with auto-continuation (like Slack/Notion).

Problem

Currently, users must manually type list prefixes (1. , 2. , - ) when creating lists in messages. This is:

• Time-consuming and error-prone
• Inconsistent with modern chat applications
• Makes it harder to create well-formatted messages

Proposed Solution

Implement smart list formatting that:

Auto-continuation when pressing Shift+Enter:

• Automatically increments numbered lists (1. → 2. → 3.)
• Automatically adds bullet points for unordered lists
• Exits list mode when pressing Shift+Enter on an empty list item

Markdown compatibility:

• Ordered lists: 1. Item
• Unordered lists: - Item
