The hook never passed the engine's selfEmail / repoPublicEmails, so every
push that added the pusher's address, or a commit author's, raised a MEDIUM
pii.email warning for an address the destination already shows.
The hook now reads `git config user.email` and one bounded `git log` of
author and committer addresses, raw and mailmapped (%ae %aE %ce %cE): the
history of every pushed tip (those commits become public with the push),
each remote tip being replaced, and, for a new branch or an unknown remote
tip pushed to a configured remote, that remote's own tracking refs. A URL or
unknown destination never borrows tracking refs, and another remote's
history never counts.
The read stops at 50,000 commits (the newest authors are used) and 5 seconds.
An error or the timeout passes no history and, when an email finding is
listed, prints one line saying suppression was limited for this push. The two
inputs fail independently. HIGH findings and every other rule are untouched.
Controls: a stranger's address, an address only another remote knows, a URL
push next to a matching remote, and a first push of a repo with no history
all still report.
Plan items: A3, CEO-7, CEO-23 (A3 half), DX-9 (partial history), ENG-8
(history scope, mailmap).
