v1.3.0 — Community icon libraries + gallery rework

✨ New

• Community shape & icon libraries (#13) — embed real AWS / Azure / GCP / network / UML / BPMN icons (200+ .excalidrawlib libraries) directly into a scene. They're built from the same vector primitives the skill exports, so they render through the Kroki / local-CLI export path — no image element, no files map. New bundled helper scripts/excalidraw_lib.py: search libraries, items (flags image-based ones), and merge an item with namespaced IDs + translated coordinates.

🖼️ Changed

• Gallery reworked (#14) — trimmed 8 repetitive box-and-line diagrams to 2 classics (flowchart, sequence) and added 4 range-showing examples: Azure web app, GCP data pipeline, network topology (Cisco-style), and a hand-drawn-style sketch.
• "How it works" now has a diagram (#12) — the skill's own pipeline (Detect → Plan → Generate → Export → Verify → Report, with a Verify→Generate loop), drawn by the skill and render-verified.
• Docs consolidated into the READMEs (#11) — folded the design-system reference, setup patch, and "why a skill, not an MCP server" out of docs/*.md and removed the redundant files.

🐛 Fixed

• Rotation- and points-aware bbox in the library helper (#15) — items with rotated sub-elements (e.g. the GCP Pub/Sub icon) now place correctly instead of drifting off-target.

Notes

• No breaking changes. The library helper needs network access at generation time to fetch a library (cached under /tmp).
