agra f13f4abfb1 fix: visibility-aware type-name resolution at registration time
Enum payloads, union fields, inline struct/enum/union field types, and
named error-set references now resolve through the visibility-aware
`inner` recursion hook (the same seam `resolveCompound` uses) instead of
the flat `findByName`. A bare type name in any of these positions now
selects the querying module's OWN author over a same-name namespaced
import -- the own-wins rule already applied to top-level named references
and struct fields.

- buildEnumInfo / buildUnionInfo / resolveInlineEnum / resolveInlineStruct
  / resolveInlineUnion / resolveErrorType take the `inner: anytype` seam;
  registerEnumDecl / registerUnionDecl and the struct-const annotation
  pass `self` (visibility-aware); resolveAstType passes the stateless `si`.
- resolveTypeWithBindings routes inline type decls and named error refs
  through `self` instead of delegating to flat resolveAstType.

Regression tests: examples/0781 (top-level enum payload over a namespaced
import), examples/0784 (inline struct field). Addresses issue 0132's
broader latent class; the protocol-return case (0132 primary) is a
separate registerProtocolDecl fix and stays open. The error-set reference
path is in place but dormant pending error-set per-decl nominal identity
(issue 0134).

// Own-wins for ENUM-PAYLOAD type registration over a NAMESPACED import.
// Regression (issue 0132, broader class).
//
// `#import "modules/std.sx"` carries the stdlib `event.Event` struct — it is
// NAMESPACED (reachable only as `event.Event`), never flat-visible. This file
// ALSO authors its OWN `Event :: struct { code }`, used as the payload of the
// enum `Wrap`. The payload type name `Event` must resolve at REGISTRATION to
// THIS file's own `Event` (which has `code`), not the namespaced stdlib struct.
//
// Fail-before: `registerEnumDecl` built the tagged-union body through the
// stateless `type_bridge.buildEnumInfo`, whose flat `findByName` picked the
// wrong same-name author — `got`'s payload became the stdlib `Event`, so
// `e.code` errored "field 'code' not found on type 'Event'". Fixed by threading
// the visibility-aware resolver (`*Lowering` as the `resolveInner` hook) through
// `buildEnumInfo` / `buildUnionInfo`, matching what `registerStructDecl` already
// does for struct fields.
