2059729 - Add getTabGroups() to TabManagementService

Status: ASSIGNED

(Core :: Machine Learning: Frontend, task, P1)

Description

[Florian Zia [:flozia]]

Summary

TabManagementService.sys.mjs already has createTabGroup() and ungroupTabs(), but no way to read tab groups. Tab group aware prompting needs a single read API so its consumers — the mentions picker, the get_tab_groups tool, and submit-time mention resolution — do not each directly access gBrowser.tabGroups and duplicate filtering rules.

Acceptance Criteria

• getTabGroups({ window }) returns open tab groups as { id, label, color, tabCount, tabs }.
• getTabGroupById({ groupId, window }) returns a single group in the same shape or null when the group does not exist.
• Grouped tabs are filtered through the same filters used by getTabList().
• Unit test coverage

Give tab group aware prompting a single read API so its consumers don't each reach into gBrowser.tabGroups and duplicate the filtering. Grouped tabs use the same isAllowedURL, isNewPageUrl, and sanitizeUntrustedContent rules as getTabList(); to share them, isAllowedURL moves into ChatUtils.sys.mjs. Includes xpcshell coverage.
