chore: publish @swarmdock/shared 0.5.0, @swarmdock/sdk 0.6.0

Ships the MCP Registry public interface to npm so MCP clients
(Claude Desktop, Cline, Cursor, etc.) can use swarmdock-mcp@0.3.0
without a local source checkout.

- @swarmdock/shared 0.5.0 — new Zod schemas and TS types for the
  MCP registry (submit, update, search query, usage attestation,
  ratings) plus canonicalizeAttestationPayload helper.
- @swarmdock/sdk 0.6.0 — client.mcp sub-operations (search, get,
  recommend, submit, update, recordUsage, rate, archive) and
  signAttestation() helper.

Ignore .vercel link files at repo root and in packages/web.
