refactor(reference): serve discovery through typert Remote faces

Replace the legacy reference.* API Proxy domain with @Remote methods on the
owning services, following the typert gateway design master adopted on
2026-08-02 (message-feedback and plugin-inventory precedents):

- FileReferenceService and SessionReferenceResolver extend TypertRemoteService;
  fileReferences/list and sessionReferenceResolver/candidates are unary Remote
  methods cancelled through the reserved trailing signal, and the candidates
  face attaches each candidate's canonical mention under the configured limit
- move the wire types to type-only ./types subpaths (FileReferenceCandidate,
  SessionReferenceMentionCandidate) and export ./typert plus ./remote artifacts
- mount both contributions in the api-remotes client assembly; ui-reference
  consumes ctx.remote instead of connection.api.references and registers zh/en
  locale dictionaries for its sections and labels
- delete the reference.* routes, schemas, map rows, client stubs, and fixtures;
  the connection fixture serves the Remote endpoints instead
- release deliverPrompt admission listeners when the agent is disposed with the
  prepared prompt still pending, and cover the reference-* RpcError codes in
  the schema spec
- add the missing tsconfig paths for the /grammar and /types subpaths (clean-
  tree vitest could not resolve @deepseek-ai/dsh-file-reference/grammar)
- regenerate the cordis catalog, capability seams, and event matrix; update the
  owning bilingual READMEs, Agent Notes, and the reference-composer golden
