F7 (operator, 2026-09-30): "Schema aliasing sounds like a really bad idea,
I support retiring it." One CLR type owns a schema, so a handle never needs
converting to another type for the same schema.
- Delete AsSchemaAlias from the document and collection handles and their
interfaces, with the MessagePack round-trip converters only it used.
- The document and collection catalogs look a typed handle up by its type.
The schema-name/version fallback existed only to find a handle of another
type and alias it.
- Tests: the MeshNoteAliasDocument fixture is deleted. Tests that used it
for publication, sync, snapshot and prediction paths now use
MeshNoteDocument; the one test that only checked alias refusal is deleted.
Catalog tests check a type with no handle is not found.
- public-api.md stops documenting aliasing; a stale comment in
ReadDocumentFromSnapshotResponse that cited the fixture is trimmed.
