mcp-ts-core 0.12.3 and MCP SDK v2 adoption

  • Serves MCP protocol revision 2026-07-28 alongside existing clients
  • Tool inputs advertise additionalProperties: false and reject an undeclared argument key by name instead of stripping it
  • outputSchema declares the error envelope; validation failures render as flat path: message sentences; an unknown tool rejects with -32602
  • ctx.log output now also reaches clients as notifications/message
  • Docker pins Bun 1.4.0, builds with --platform=$BUILDPLATFORM, and installs with --omit=peer; tsconfig splits src/tests typecheck from build emission
  • deps: @cyanheads/mcp-ts-core ^0.11.1 → ^0.12.3 (+ Biome, TypeScript, Vitest, tsc-alias, DuckDB bumps)
