docs: enhance JSDoc standards and document package structure

[watson]

Enhances the developer documentation to improve clarity around JSDoc standards and document the standard package structure. Updates both AGENTS.md (AI agent guidelines) and CONTRIBUTING.md (human contributor guidelines) to maintain consistency.

For AI agents (AGENTS.md):

1. Package structure wasn't documented - Added explicit documentation of the standard src/ and test/ directory layout with *.spec.js naming conventions used consistently across all packages. This helps agents quickly understand project organization.

2. JSDoc standards needed better visibility - Separated JSDoc into its own subsection (was buried as a single bullet point) and added explicit guidance to never use the any type, which helps agents maintain type safety.

3. Removed duplicate guidance - The Node.js core module prefix requirement was already covered in the Import Ordering section.

For human contributors (CONTRIBUTING.md):

• Aligned JSDoc documentation to match AGENTS.md, including the explicit rule against using any type in JSDoc annotations.
