Function attribute_commits_after_ingest

src/sessions/mod.rs:108–116

Runs the bounded commit-attribution sweep against the correlation store. For each `(branch, worktree)` pair touched since the last sweep, scans that branch's git log inside the pair's span window (widened by the merge gap) and attributes overlapping commits to their sessions. Fail-open.
