Release 17.0.0-beta.6 (#25) - Add CLI E2E tests, container mode, temp…

[hifi-phil]

…late fixes, and skill improvements

Comprehensive E2E testing for the create-mcp-server CLI, bug fixes found during manual testing, a new container mode for wrapping MCP servers, and template/skill improvements from real-world usage feedback.

CLI Bug Fixes

• McpOAuthComposer.cs: Try-catch resilience so Umbraco starts before DB is ready (unattended install)
• setup-instance.ts: Write connection string to appsettings.local.json, unattended install config to appsettings.Development.json, patch Program.cs to load appsettings.local.json
• Template TS errors: Fix createToolResult signature, jest.fn typing in server-config.test.ts
• collections.ts cleanup: removeExamples() now cleans up collections.ts imports

E2E Tests

CLI E2E (19 deterministic steps, cli-e2e.test.ts):

• Scaffold → init (Forms + SQL Server) → start Umbraco → API user creation → token verification → swagger discovery → .discover.json → generate client → TypeScript compile → unit tests → integration test against real Umbraco → real API calls → hosted worker

Container Mode E2E (5 steps):

• Scaffold → remove API tools → compile → build → worker starts

Skill E2E (3 steps, skill-e2e.test.ts, opt-in via RUN_SKILL_TESTS=true):

• /build-tools creates Language collection that compiles
• /build-tools-tests creates integration tests
• Integration tests pass against real Umbraco

Infrastructure: Random SQL Server database per run, KEEP_E2E_ASSETS=true for preserving project between runs, test:e2e:revert for resetting skill output, test:e2e:cleanup for teardown.

Container Mode

New init prompt choice: "Container mode — wrap other MCP servers via chaining, no direct API tools"

• removeApiTools() strips orval, generated client, example tools while keeping chaining infrastructure
• Tool mode question comes after Umbraco instance setup (instance always needed for OAuth)

Template Improvements

• Self-signed certs in Jest: Override globalThis.fetch with undici's fetch (Node 22's built-in fetch ignores NODE_TLS_REJECT_UNAUTHORIZED in Jest VM sandbox)
• MSW conditional: Gate setupMswServer() behind USE_MOCK_API=true (was blocking real API calls in integration tests)
• .gitignore: Added to template (demo-site/, .env, appsettings.local.json, .discover.json)

Skill Improvements

• build-tools: Compile after EACH tool file, not batch
• build-tools-tests: Complete working builder example with delete/cleanup, anti-pattern warning for result.content[0].text (must use createSnapshotResult), initializeUmbracoFetch in setup.ts template, read-only collection guidance
• count-tools: Replace glob npm package with Node 22 built-in fs.globSync
• Plugin install: Correct commands in discover output (/plugin marketplace add + /plugin install)
