The global pre-push hook, the /sh-security-review prompt, and finding.schema.json
previously lived only in ~/.config/git and ~/.claude (untracked) — unreproducible.
Source them here: add hooks/pre-push, rewrite install-hooks.sh with a --global mode
(lays down both hooks, sets core.hooksPath, links skill+schema into ~/.claude) and a
per-repo mode. Align pre-commit with pre-push (honor skip marker + suppressions). Add
semgrep p/javascript so the scanners cover the org's Node/.NET repos.
