2013393 - Implement search handoff Option 1 - automatic run_search tool with SERP content retrieval, reworked

Status: RESOLVED FIXED

(Core :: Machine Learning: General, enhancement)

Description

[again]

Implement Option 1 (Ideal Happy Path) of the search handoff feature for Smart Window:

• Add run_search(generated_query) tool call that:
  1. Generates Google SERP URL from the query
  2. Opens the SERP in the main tab (moves chat to sidebar if fullscreen)
  3. Retrieves page content
  4. Returns content to LLM to continue the conversation

See Search Handoff Doc for full options comparison.

This is a rework of https://bugzilla.mozilla.org/show_bug.cgi?id=2011900 due to a patch that landed with overlapping functionality.

Attachment: Bug 2013393 - Implement search handoff with run_search tool ? r=ai-frontend-reviewers,ai-models-reviewers,bjohns,omarg

Add run_search tool that navigates the main tab to a SERP, extracts
page content, and returns it to the LLM to continue the conversation
in the sidebar.

This a new reworked patch of search handoff: This fixes some bugs, adds more tests, reuses components introduced in a recent patch, and addresses some prior comments in the prev patch.
