Extract CLI into @eventcatalog/cli package

[boyney123]

What This PR Does

Extracts the CLI from @eventcatalog/sdk into a new standalone @eventcatalog/cli package. This gives cleaner separation of concerns — the SDK remains a pure programmatic API, while the CLI lives in its own package with its own dependencies (e.g. commander).

Changes Overview

Key Changes

• New packages/cli/ package — contains CLI entry point, executor, list command, argument parser, and cli-docs registry
• SDK cleanup — removed bin field, commander dependency, ./cli-docs export, and CLI source/test files from SDK
• Updated imports — CLI now imports createSDK from @eventcatalog/sdk instead of relative ../index
• CI/CD updates — verify-build.yml now packages and uploads the CLI artifact; turbo.json adds dependsOn: ["^build:bin"] to ensure correct build ordering
• README updates — SDK README trimmed to SDK-only content with link to CLI; new CLI README with full CLI documentation

Packages affected

• @eventcatalog/cli (new, minor)
• @eventcatalog/sdk (patch — removes CLI, no API changes)

How It Works

The CLI package depends on @eventcatalog/sdk via workspace:* and re-exports the same eventcatalog binary. All CLI source files were moved with imports updated from relative SDK paths to the @eventcatalog/sdk package import. Tests were moved alongside and mock paths updated accordingly.

Turbo's build:bin task now uses dependsOn: ["^build:bin"] so workspace dependencies (SDK) always build before dependents (CLI).

Breaking Changes

• @eventcatalog/sdk no longer provides the eventcatalog binary — users should install @eventcatalog/cli instead
• The @eventcatalog/sdk/cli-docs export has moved to @eventcatalog/cli/cli-docs

Test Plan

• pnpm run build:bin — all 5 packages build successfully
• node packages/cli/dist/cli/index.js --help — shows help
• node packages/cli/dist/cli/index.js list — lists SDK functions
• SDK tests: 488 passed (16 files)
• CLI tests: 22 passed (3 files)
• @eventcatalog/cli@0.1.0 published to npm
