Add a new private TypeScript package at src/delegated-user-auth/ that implements the MCP extension `io.modelcontextprotocol/delegated-end-user-context` as a readable, well-commented reference for other developers. The package includes: - extension.ts: shared wire contract (Zod schemas, error builders, redaction) - policy.ts: frozen default policy catalog + pure intersection (never widens) - data.ts: fake user data, identity canonicalization, scope→field projection - jwt.ts: in-repo IdP via jose with test-controllable minting and typed errors - server.ts: low-level Server with override-initialize, inline authorizeRequest, and all tool/resource handlers; requires a server-owned trusted-issuer allowlist - client.ts: agent-platform client with per-instance overrides and _meta injection - demo.ts: in-memory walkthrough (phases 1–7) with redacted printing - index.ts: launcher - 74 invariant-focused tests and a tutorial README Also add the spec file (delegated-user-auth.md) and update .gitattributes to suppress the indent-with-non-tab whitespace check for package-lock.json (npm uses space indentation throughout the lockfile).
