Commit Message

editors: language-aware CodeMirror panes for the web apps, with error anchoring

Implements doc/editor-integration-plan.md phases 0-3 (see that doc for
architecture and remaining phase-4 items).  New code is TypeScript
(src/*.ts -> committed lib/, built by make ALL / per-package npm run
build; typescript is now a root devDependency instead of an assumed
global tsc).

parser (@shexjs/parser):
- tripleConstraint productions record identity-keyed source ranges in
  schema._exprLocations (anchored on senseFlags/predicate to dodge the
  empty-production location wart).  Validation errors reference these
  same objects, so error mapping is an identity lookup.
- addSourceMap now records the production's own location: _sourceMap
  ranges used to point at the lookahead token; @<ref> sites now cover
  the whole reference.
- _exprLocations whitelisted in the schema visitor and stripped in
  AStoShExJ/canonicalization alongside _locations/_sourceMap.

@shexjs/editor-services (new package, TypeScript):
- editor-services: parseShExC/locateInParsed/parseTurtle (millan
  github:ericprud/millan#rdfjs-interface, whose RDF/JS terms carry
  source provenance)/mapValidationErrors -- CodeMirror-ready
  {from, to, severity, message} diagnostics with paired schema/data
  anchors.  locateInParsed exists because @shexjs/loader's
  import-merging makes a new top-level Schema but shares the inner
  expression objects.
- editor-panes: CodeMirror 6 glue.  makePane replaces a textarea while
  keeping it as a live value proxy (property override), so caches,
  permalinks, drag-and-drop and tests are unaffected; panes dispatch
  both change and synthetic keyup because the apps' cache
  dirty-tracking listens for typing -- without keyup, validate re-used
  the previously parsed text while live lint squiggles stayed current.
  Stream-tokenizer ShExC mode; Turtle/JSON modes; highlight API.

web apps:
- editors are a Menu -> 'user interface' select, carried as ?editors=1
  in permalinks, ... (continued)
