Subject: [PATCH v2 5/7] builtin/repo: add inflated object info to structure table

From: Justin Tobler <[email-masked]>
Date: Fri, 12 Dec 2025 16:36:42 -0600

Update the table output format for the git-repo(1) structure command to
begin printing the total inflated object size info by object type. To be
more human-friendly, larger values are scaled down and displayed with
the appropriate unit prefix. Output for the keyvalue and nul formats
remains unchanged.
