Upgrade Astro/Starlight to latest versions

[Adammatthiesen]

This pull request updates dependencies, refines the sidebar configuration, and makes some plugin adjustments to improve compatibility and maintainability. The most important changes are grouped below:

Dependency Updates and Compatibility

• Upgraded several core and integration dependencies in package.json, including astro, @astrojs/starlight, @shikijs/colorized-brackets, and related Starlight plugins, to their latest versions for improved features and bug fixes. Also added @astrojs/markdown-remark and updated @fontsource-variable/onest for better font support. [1] [2]
• Removed the expressive-code-twoslash plugin from ec.config.mjs (commented out) due to incompatibility with the latest Astro/Starlight/Expressive Code versions, with a note to revisit in the future.
• Updated pnpm-workspace.yaml to exclude new Astro-related packages from minimum release age checks, improving release workflow flexibility.

Sidebar and Navigation Structure

• Refactored the sidebar configuration in astro.config.ts to use the items array for autogenerated sections instead of the previous direct autogenerate property. This change aligns with the latest Starlight sidebar schema and ensures future compatibility. [1] [2] [3] [4] [5] [6] [7]

Markdown Processing

• Integrated the @astrojs/markdown-remark unified processor into the markdown configuration in astro.config.ts for enhanced markdown processing capabilities and plugin support. [1] [2]

These changes collectively ensure the project stays up-to-date with the latest ecosystem improvements, maintains compatibility, and adopts best practices for configuration and extensibility.

📝 Walkthrough

Walkthrough

The PR updates Astro and Starlight dependencies, disables the two-slang plugin, changes Markdown processor configuration, restructures sidebar autogeneration entries, updates release-age exclusions, and changes the TypeScript path alias.

Changes

Astro configuration updates

Layer / File(s)	Summary
Dependency and build configuration package.json, pnpm-workspace.yaml, ec.config.mjs, tsconfig.json	Dependencies and workspace exclusions are updated. The two-slang plugin is disabled. The ~/* TypeScript alias now maps to ./src/*.
Markdown and sidebar configuration astro.config.ts	Markdown plugins now run through unified. Sidebar autogeneration entries use nested items arrays, and ecosystem/packages is collapsed by default.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 5fb62

The dependency policy now allows all packages in several Astro-related scopes to bypass the 72-hour release-age protection, which modestly broadens supply-chain exposure and should have explicit owner awareness. The PR is otherwise mergeable with follow-up to narrow or document these exceptions.

Poem

A rabbit checked the Astro chart
New paths and plugins took their part
Sidebars nested, neat and bright
Markdown hopped through unified light
Dependencies settled right
