chore: fill or remove RSR template placeholders (#78)

`openssf-compliance.yml` fails when any of the thirteen files it checks
still contains a `{{PLACEHOLDER}}` token. This clears them, with no
invention.

- **Deleted** the `TEMPLATE INSTRUCTIONS (delete this block before
publishing)` comment — the template says to delete it, and it is where
every legend line lived, so a large share of the reported tokens were
the file documenting its own placeholders.
- **Filled** what the repository itself supplies: owner and repo from
the git remote, project name, year, forge, main branch, contact email.
- **Removed** PGP and website lines. `https://github.com/<user>.gpg`
returns HTTP 200 for every account; with no key uploaded the body is a
stub reading *"This user hasn't uploaded any GPG keys"*. No key is
published for either account, and commit signing here is SSH —
unrelated. The template sanctions this: *"Optional: Remove sections that
don't apply (e.g. PGP if you don't use it)."*\n\nA security policy
telling a researcher to encrypt to a key that does not exist is worse
than one that does not mention encryption.\n\n**Where applicable, this
also fixes a misrouted advisory URL.** A previous `just init` copied
already-filled templates out of `squisher-corpus`, so 51 repositories
directed vulnerability reports to `hyperpolymath/squisher-corpus` — a
repository unrelated to the code being reported, meaning the affected
maintainer never saw them. Repointed from this repository's own git
remote.
