v0.11.2-alpha.1

build(deps): bump the npm-minor-patch group with 13 updates (#308)

Bumps astro-eslint-parser 3.2.0, prettier 3.9.9, prettier-plugin-astro 1.1.0, mdast-util-to-markdown 2.1.3, @anthropic-ai/claude-agent-sdk 0.3.283, posthog-js 1.434.15, posthog-node 5.54.1, chromatic 18.9.5, @astrojs/starlight 0.42.4, @iconify-json/lucide 1.2.137, astro 7.3.5, motion 13.4.4, and sharp 0.35.5.

Holds @vercel/og at 1.0.1: 1.0.3 still ships the Satori/HarfBuzz build that breaks Astro prerendering (vercel/satori#794), so it joins 1.0.2 in the Dependabot ignore list.
