Add a large blob check to the pre-push hook, using the same git tree
diff logic as corp's check-file-size CI workflow (the
check-git-accidental-large-file GitHub Action): diff the pushed tree
against the remote's old tree (or the merge base with the remote's
default branch for new refs) and reject any new or changed blob over
1.5 MB. Unlike the CI check, which only guards PRs into main, the hook
runs before pushing to any branch, catching mistakes before they
permanently bloat the remote repo.
Set TS_SKIP_LARGE_FILE_CHECK=1 to push a large file intentionally,
mirroring the skip-large-file-check commit message tag honored by CI.
This folds the go.mod replace check and the new check into a single
CheckPrePush entry point so both share one read of the hook's stdin;
corp's git-hook.go needs the matching call site update when it next
bumps its tailscale.com dependency.

Pull the hook logic into a reusable githook library package so
tailscale/corp can share it via a thin wrapper main instead of
keeping a forked copy in sync.
The install flow also changes: a wrapper scripts now build the
binary and reinstall the git hooks. Pulling new shared code no
longer requires re-running the installer.
