Commit Message

editors: phase-4 -- worker-safe anchoring, autocomplete, materialization marks

Worker-app error mapping without worker changes: every error leaf now
carries its predicate, so the (shape, predicate) lookup anchors
validation errors even when postMessage's structured clone breaks object
identity with the schema.  Tested against a JSON round trip of the
results.

Single-parse: parseShExC/parseTurtle memoize their most recent results
(small LRU keyed on text+base); the live linter and the validation-time
mapper share one parse.  RdfJsDb(MillanDataset) as the validation store
remains open -- the app's proof-graph/remainder/slurp flows use
N3-specific APIs and N3 internalization would drop term sources (noted
in doc/editor-integration-plan.md).

Materialization-failure anchoring: ThreadedMaterializer failure records
reference their TripleConstraint (kept out of the error message JSON);
ShExMapBaseApp.anchorMaterializationFailures resolves them by identity
into outputSchema-pane diagnostics ('no binding for <bp:sysVal>' lands
on the exact constraint), clearing on success.  MaterializationErrors
are tagged as input errors for the console policy.  Main-thread app
only; the worker materializer still ships just a message.

Autocomplete: ShExC and Turtle panes complete prefixes (namespace as
detail), shape labels (plain and @ref forms) and constraint predicates,
supplied live from the parsed schema (_index labels, _exprLocations
keys) and both panes' prefix maps; the shexmap outputSchema pane
completes from its own schema.  Wired through CodeMirror languageData
so basicSetup's autocompletion picks it up; completionSource and
lexicalize are unit-tested via a programmatic CompletionContext.

Tests: 5044 passing.
