docs: weekly contributor tally refresh + cherry-pick credit accuracy fix (#4473)

* docs: weekly contributor tally refresh (20260619)

Regenerated by scripts/regen_contributors.py --apply. Includes the source (e)/(f)
ship-signal accuracy fix that recovers systematically-undercounted cherry-picked
contributions (~77 contributors). 280 contributors / 1559 credits (was 263/1232).
Markers spliced, prose untouched, --verify clean, 0 double-counts.

* docs: align CONTRIBUTORS header prose with the 5-source credit algorithm

Addresses greptile P2: the header still described the old three-source union
(merged-PR list + CHANGELOG + Co-authored-by) but regen_contributors.py now adds
two more — ship-comment scans and absorb-commit scans — for five total. Updates
the prose to match what the script actually runs.
