Enable Second-Level Replies and Reactions on Hangout Post Comments

Description:
Currently, Hangout post comments support only a single level of replies, which limits deeper conversations and structured discussions. Users are unable to reply to replies (second-level replies), making it difficult to maintain context in threaded discussions.

Additionally, reaction options (e.g., like, love, etc.) are not available on replies, which reduces engagement and feedback visibility on individual responses.

Proposed Enhancement:

1. Introduce second-level reply functionality, allowing users to reply to existing replies within a comment thread.
2. Enable reaction options on replies, similar to reactions available on main comments or posts.

Expected Benefits:

• Improves conversation clarity and structure
• Encourages deeper user engagement
• Enhances user experience by enabling expressive feedback on replies
• Aligns with common social platform interaction patterns

Acceptance Criteria:

• Users can reply to a reply (nested at least two levels deep)
• Replies display in a clear threaded format
• Reaction options are visible and functional on replies
• UI remains clean and readable despite added nesting

Priority: Medium

Notes:
Consider implementing limits on nesting depth or UI indentation to maintain readability.
