Stdlib UUID (go1.27) - #77
Merged

Conversation
Go 1.27 introduces a stdlib uuid package. Its uuid.UUID resolves to
{type: string, format: uuid} by type identity — import path plus name,
alongside the existing time.Time and json.RawMessage checks — so it is
recognized wherever a named type is handled, not only where the fuzzy
name heuristic runs. That heuristic stays as the fallback for the
third-party UUID types (google/uuid, gofrs/uuid, strfmt.UUID), and an
explicit swagger:strfmt still overrules both.
The recognizer carries no build constraint, on purpose: codescan
compares types harvested from scanned sources and never imports uuid
itself, so a binary built by an older toolchain must still recognize a
go1.27 user type. Only the fixture and its integration test are guarded
by //go:build go1.27, since those genuinely cannot compile before then;
the predicate keeps its coverage on every supported toolchain through a
unit test that synthesizes the type instead of importing it.
An embedded uuid.UUID is unaffected — a non-struct, non-interface embed
still falls to the unsupported-type warning and contributes nothing.

The model definitions tutorial now states the two rules side by side:
the go1.27 standard-library uuid.UUID matched by type identity, and any
other text-marshalling type named UUID matched by name. Both publish
{type: string, format: uuid}, and swagger:strfmt overrules either.
