Would you take a pull-request security scan workflow?

Would a pull-request security scan be useful here, or is this already covered?

One workflow. On each pull request it scans the checked-out repository for
hardcoded credentials, injection, SSRF and unsafe deserialisation, and writes
findings to the Security tab. Report-only — findings never fail the build.

Two files under `.github/`, a pinned `@profullstack/threatcrush@0.11.1` whose tarball is hashed before
install, and `pull_request` rather than `pull_request_target`.

A pull request is open alongside this with the diff, if reading it is easier
than discussing it.

MIT and free. Written with AI assistance. Closing this is a fine answer and I
will not ask again.

Start by reading the open pull request and the two workflow files under `.github/`; the issue gives the intended scan scope and safety constraints. Verify that the workflow runs on `pull_request`, pins and hashes the ThreatCrush tarball, remains report-only, and publishes findings to the Security tab.
