feat(git): view submodule working-tree changes in the Git panel

Browse Source 
Recurse into dirty submodules when building the Git status so their
modified and untracked files appear as full-path entries, and add a
commit-pointer entry (with short SHAs) only when the recorded commit
actually moved. Route diffs whose path falls inside a submodule to run
in that submodule's working tree so real per-file diffs are shown.

The changed-file list groups these under the submodule: tree view keeps
the nested structure and marks the submodule root with a badge, list
view flattens them into one expandable group pinned above the ordinary
files. Depth 1 only; ignored files are excluded; the panel stays
read-only.

Covered by client tree/list-grouping tests, parser tests, and a
server test that drives a real temporary repository and submodule.

Expand a changed submodule in the Git panel to see the work inside it. Tree view nests the submodule's own modified and untracked files (keeping their folder structure) and list view flattens them into one group, with a moved commit pointer shown as `<old> → <new>` when it changed. Selecting any inner file shows its real diff instead of the bare `Subproject commit` line.
