chore: sync README + CHANGELOG with the 3 packages registered today (#21)

After today's wave (#16 EchoTypes + KRLAdapter, #18 ViperPkg, #20
EchoTypes v0.2.0) Registry.toml carries 37 packages, but README's
table and the [Unreleased] CHANGELOG section both reflected the
pre-wave 34-package snapshot. Catch up the human-facing listings:

  README.adoc: add EchoTypes, KRLAdapter, ViperPkg rows
               (alphabetical insertion; EchoTypes pinned at v0.2.0
                per the registered head, the other two at v0.1.0).

  CHANGELOG.md [Unreleased]:
    Added       — registry entries for the 3 packages
    Changed     — the scorecard.yml regression fix from PR #19
    Wiki line   — actual page count (9 + _Sidebar) and missing
                  Registering-a-Package + Security pages noted
    ISSUE_TEMPLATE list now matches what was actually added
                  (package_registration replaces "custom")
