docs(governance): fill required-file placeholders + fix project naming

Remove unfilled {{PLACEHOLDER}} tokens from the openssf-compliance gate's
required-file set so the gate passes, without touching legitimate template
files (k9 *.ncl, contractiles, container/well-known stubs, e2e templates).

- .machine_readable/ECOSYSTEM.a2ml: fill {{REPO_DESCRIPTION}} with the KRL
  one-line description from README.adoc.
- .github/SECURITY.md: delete the rsr-template TEMPLATE INSTRUCTIONS block;
  remove the optional PGP section (no PGP key — {{PGP_KEY_URL}}/
  {{PGP_FINGERPRINT}} had no fill value, and the template marks PGP optional).
- .github/CODE_OF_CONDUCT.md: delete the TEMPLATE INSTRUCTIONS block (body
  already instantiated for krl).
- .machine_readable/6a2/STATE.a2ml: drop META-TEMPLATE comment scaffolding
  referencing {{PLACEHOLDER}}; body already instantiated for krl.
