v0.1.0 — registry, packages, and CKGP v1 spec are live

[amacsmith]

v0.1.0 is out, and the project now lives across five distribution surfaces.

What shipped:

• Registry + Pages site — registry.json with schema-validated entries, a searchable browser, a force-directed graph viewer, and a four-field "add your repo" wizard at https://looptech-ai.github.io/understand-quickly/.
• @looptech-ai/understand-quickly-cli on npm — npx @looptech-ai/understand-quickly-cli add autodetects id, format, and graph URL from any repo.
• @looptech-ai/understand-quickly-mcp on npm — MCP server exposing list_repos, get_graph, search_concepts. Also listed in the MCP Registry as io.github.looptech-ai/understand-quickly.
• understand-quickly on PyPI — Python SDK: Registry().list(status="ok").
• looptech-ai/uq-publish-action — GitHub Action that stamps graph metadata and fires repository_dispatch for instant resync. Listed on the Marketplace.

CKGP v1 spec is live. The Code-Knowledge-Graph Protocol formally defines the producer side (.well-known/code-graph.json), the registry contract, and the multi-vendor expectation. CKGP is a protocol, not a service; this registry is one reference aggregator. Read it: docs/spec/code-graph-protocol.md.

Upstream integrations. 12 producer PRs are open across Understand-Anything, GitNexus, code-review-graph, Repomix, gitingest, codebase-digest, deepwiki-open, OpenDeepWiki, graphify, codebase-memory-mcp, and pocketflow-tutorial-codebase-knowledge. One has merged so far. PR drafts and the producer protocol live in docs/integrations/.

Formats supported today: understand-anything@1, gitnexus@1, code-review-graph@1, bundle@1 (for repo-context packers), and the generic@1 fallback.
