Requirement or Bug

Allow desktop session information to query Git status independently for every folder in a multi-root workspace.

Bug Reproduction Steps

Root Cause

Code Changes

Git status request
  ├── no root: keep the existing primary-workspace behavior
  └── root present
      ├── validate that root is a directory inside the workspace
      ├── resolve its containing workspace and runtime, including additional dirs
      ├── run Git status and numstat only for that folder
      └── resolve the branch and PR, preserving draft state

The request schema now accepts an optional root. Existing callers that omit it retain the current primary-workspace semantics and file filters.

Behavior Changes and Affected Users

Behavior	Before	After	Who relies on the old behavior	Escape hatch
Git status without root	Uses the primary workspace root and existing file filters	Unchanged	Existing daemon clients and the current Changes panel	Existing behavior and tests remain in place
Git status with root	The field was ignored, so additional folders reused primary-root data	Selects and scopes the requested folder, including additional workspace dirs	New desktop folder-level session information	Not applicable
Numstat for a selected root	Included changes from the whole repository	Includes only changes under the selected root	Desktop users comparing multiple folders in one repository	Omit root to retain repository-wide primary status
Draft PRs	Reported as open	Reported as draft when isDraft is true	PR status consumers	Other PR states are unchanged
Additional-dir runtime resolution	Could report that the workspace was not materialized	Resolves the workspace containing the requested directory	Multi-root workspaces	Primary-root resolution is unchanged
