Deferred from the original web MVP. git blame rendered per file with commit links and signature-aware attribution; plumbing exists (cat-file/log), needs a handler, template, and pagination for large files.

Shipped in 3cc47d6 and live: /owner/repo/blame/ref/path renders porcelain blame as grouped hunks with linked commit subject, short sha, author, date, and signature badge; 1000-line pages via -L ranges; blame link on blob pages; binary and empty files handled. Verified locally (light/dark, 375px, no horizontal page scroll) and on gitbay.org.
