Greptile Summary

This PR adds ADK and Desk sections to the main docs sidebar, introduces two new documentation stub pages (adk/quickstart.mdx and desk/introduction.mdx), fixes a runtime-breaking typo in the chevron icon constant names in code-copy.ts, and swaps the link icon in Step.astro from the project's Icon.astro wrapper to a direct lucide-react import.

• Sidebar config (bach.config.ts): Two new sidebar groups (ADK, Desk) pointing to the new pages — straightforward addition.
• Bug fix (code-copy.ts): Corrects CHEVRON_DOWN_ICON_ICON / CHEVRON_UP_ICON_ICON to CHEVRON_DOWN_ICON / CHEVRON_UP_ICON, which didn't match the actual exports and left the expand/collapse labels broken at runtime.
• Step icon (Step.astro): Switches from Icon.astro to a raw lucide-react component; functionally equivalent, but slightly inconsistent with the rest of the codebase's icon conventions.

Confidence Score: 5/5

Safe to merge — the changes are additive documentation stubs with a targeted bug fix; no existing functionality is broken.

The only substantive code change is fixing the typo in chevron icon import names, which was clearly broken before. The new docs pages are stubs that don't touch any shared logic. The Step.astro icon swap works correctly at runtime.

No files require special attention, though it's worth confirming whether the unused images in src/content/docs/adk/assets/ are intentionally deferred or accidentally omitted from the MDX page.

Important Files Changed

Filename	Overview
src/components/Step.astro	Replaces custom Icon.astro with a direct lucide-react Link component; className is correct for React in Astro, and size-3 now applies without conflicting with Icon.astro's forced size-4.
src/scripts/code-copy.ts	Fixes typo in imported constant names (CHEVRON_DOWN_ICON_ICON → CHEVRON_DOWN_ICON, CHEVRON_UP_ICON_ICON → CHEVRON_UP_ICON) to match actual exports; the old names were undefined at runtime, breaking expand/collapse.
src/content/docs/adk/quickstart.mdx	New ADK quickstart stub with a Card linking to /adk; two image assets were added to the same directory but are not referenced in this file.
src/content/docs/desk/introduction.mdx	New Desk introduction page with feature list and contact CTA card; content and Badge usage look correct.
bach.config.ts	Adds ADK and Desk sidebar groups pointing to the two new documentation pages; straightforward config addition.
