Subject: [PATCH] Add A2ML and K9 MIME types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add two new vendor MIME types:

- application/vnd.a2ml (*.a2ml) — A2ML Attested Markup Language,
  a TOML-like structured metadata format used for machine-readable
  project state, ecosystem, and attestation files.

- application/vnd.k9+nickel (*.k9, *.k9.ncl) — K9 Self-Validating
  Component, a Nickel-based format with three security tiers
  (Kennel/Yard/Hunt) and a "K9!" magic number at offset 0.

Both formats are text-based. A2ML is a subclass of text/plain.
K9 files use the "K9!" magic number for reliable content detection.

Includes test files for both formats.

- K9 spec: https://github.com/hyperpolymath/standards/tree/main/k9-svc
