More agents and tools components

Tool Call Card
Shows that the AI used a tool, with its name, status and time. Open it to see the exact input and the result it got back.
Action Approval Request
Before an agent does something important, like sending an email, it shows exactly what it will do and waits for Allow or Deny.
Editable Task Plan
The agent proposes a step by step plan before it starts. People can reorder, edit or remove steps, then approve the plan to run it.
Agent Activity Timeline
A timeline of everything an agent did: its thinking, tool calls, results and messages, with times and a filter by type.
File Change Preview
Shows the changes an AI wants to make to a file, with removed lines in red and added lines in green, and buttons to accept or reject.
Web Results Card
A card listing the web pages an AI read, with title, site and a short excerpt. Pages it used in the answer are marked.
