- @cyanheads/mcp-ts-core ^0.8.20 → ^0.9.1: server-level `instructions`
  on createApp (mcp-ts-core#91), portability lint family
  (mcp-ts-core#132), Workers nodejs_compat boot (mcp-ts-core#124),
  build-time-only definition linting, SSRF DNS+IPv6 hardening,
  FileSystemProvider tenantId boundary check, rate-limit metric
  cardinality bound, notifyPromptListChanged/notifyToolListChanged on
  Context, tasks capability gated on actual usage.
- src/index.ts: adopt the new `instructions` block — orientation text
  on every initialize covering NCT ID format, PascalCase field-leaf
  naming for fields/advancedFilter/sort, the typical workflow, and
  the discovery tools. Spec-compliant clients forward it as session-
  level system context to the model.

  outdated parser fix synced from framework.
