feat(twitter): add time column to search output

[voidborne-d]

Summary

Adds a time column to the twitter search command output, showing when each tweet was posted.

Changes

• Extract created_at from tweet.legacy.created_at (RFC 2822 format)
• Parse into ISO-like YYYY-MM-DD HH:MM:SS for readability
• Add time column between text and likes in output
• Graceful fallback: keeps raw string if date parsing fails

Why

When monitoring trending topics, users need timestamps to filter out old tweets. Without this field, there is no way to distinguish a tweet from today vs. one from last week.

Example output with the new column:

id          author    text              time                 likes  views  url
192837465   @user1    Breaking news...  2026-03-26 10:30:00  42     1200   https://x.com/...

Closes #465

Nice addition, timestamps for search results make a lot of sense. A couple of things I noticed:

Field naming: the other twitter commands (timeline, likes, bookmarks, thread, profile) all use created_at for the same concept. Using time here means JSON output keys differ across commands, which could trip up scripting.

UTC without timezone indicator: toISOString().slice(0, 19) produces UTC time but drops the Z suffix, so 2026-03-26 10:30:00 looks like local time but is actually UTC. The comment also says "local timestamp" which adds to the confusion. Keeping Z or noting "UTC" in the column name might help.

Both are minor, the core change is solid.
