repo: add paths.toplevel to repo info

jayesh0104 · jayesh0104 · commit 448dfae6a15e · 2026-04-02T16:25:08.000Z
Expose the working tree root via `git repo info` as
paths.toplevel, matching the semantics of
`git rev-parse --show-toplevel`.

For bare repositories, this value is empty, consistent
with other non-applicable fields.

This allows scripts to retrieve the repository root
through a structured interface without invoking
rev-parse.
