feat(tui): reconcile scoped selection and publication lifetimes

Reuse canonical escaped absolute reference labels; retain structured operation selection across loading and row movement. Freeze editor targets and retire confirmation on Client observation invalidation. Mirror retained stale/loading Object, tree and Interface state without ref fabrication or automatic execution.

Validation: 36 TUI unit tests, real filesystem HTTP workflow, 8 formatter and 6 asynchronous runtime tests, and 2 doc-tests pass. Full workspace fmt/check/all-target tests/doc-tests, Nix clippy -D warnings, rustdoc -D warnings, public example and diff check pass. Scoped regressions cover same-name dispatch, stale/ref-less/replaced/deleted scopes, old in-flight contexts and selective typed-entry observation.

+### Rust API and wire migration
+
+Interface identities in the presentation map, action/selection rows, in-flight
+subjects and editors are now `InterfaceReference { scope, name }`, not strings.
+This is a breaking Rust API change; consumers must construct an explicit canonical
+absolute scope rather than parse a label or infer a scope from a target Entry.
+`ArgumentEditor` also retains its Entry `path`; `new` defaults to `/`, and
+`for_target(path)` fixes the chosen target before editing. Normal UI selection
+sets it automatically. Confirmation never retargets an existing editor.
+`App::operation_selection` retains the Entry and structured row through temporary
+loading gaps; the numeric cursor is only a layout position. Retaining this subject
+does not expose stale operations or authorize execution.
+
+The TUI uses the scoped Protocol/HTTP Client wire: Interface references are
+structured, and calls use an Interface target carrying the reference and optional
+`scope_ref`/validator preconditions. The optional identity is copied by the Client,
+not invented by the UI; no additional required ref is introduced. This wire is not
+compatible with the former string-reference request/response shape.

+Every Client transition is mirrored into retained UI Object, tree and Interface
+state, including scope retirement and cache removal. An open editor/confirmation
+is bound to private Object/Interface snapshots (not displayed refs/validators).
+Changed, stale, loading, removed or retargeted observations retire the editor;
+reobservation never recreates or executes it. Descriptor rows remain identified
+by the structured reference when another Interface gains or loses operation rows.
+Explicitly select/load an Interface header to refresh a retained stale descriptor,

+retain their original immutable context and are never moved to a new scope.

+Without refs, a same-path replacement with indistinguishable public metadata
+cannot always be detected; the UI does not synthesize identity or infer deletion
+from missing tree edges. Optional refs remain optional. Typed `Entry` results are
+only observed when individually selected; the UI neither bulk-fetches result
+paths nor adds guessed parent/indexable edges.

 For an unknown outcome, the UI states that execution or side effects may have
 occurred, marks the related Entry stale, and tells the user to refresh. Refreshing
 does not recreate the call: the user must select the operation, review fresh input,
