Bring the Rust git panel to TS parity across four surfaces:
- Commit rows expand inline into a semantic diff card (ported
diffDocuments / indexNodesById / engineDiff over serde_json::Value)
instead of navigating to a separate diff page; the card shows the
"~modify N nodes" summary plus a per-node patch list. blob_at_commit
reads the {rev} and {rev}^ blobs to compute base-vs-next.
- Overflow menu (...) with the 5 TS actions — switch tracked file, clear
commit author, remote settings, SSH keys, close repository — backed by
GitOverflowView subviews (tracked-file picker + SSH-keys list) and
remote-settings rows (origin URL + ahead/behind + fetch; no HTTPS token
field, matching TS).
- Commit signature form: empty commits are refused, and committing with no
configured author opens an inline name/email form (Enter saves, Escape
cancels) that writes the repo-local identity before retrying the commit.
- Polish: taller commit-detail card, removed panel shadow, lengthened the
ready panel, and unified the commit-textarea caret blink to the app's
500 ms cadence.
New overflow/SSH/author/remote labels resolve via Document::t with an
English fallback for keys not yet in the locale tables.
