…5851) * chore: update and streamline publishing workflow for new monorepo structure Refactors the publishing and release management workflow to support the dual-generation monorepo architecture: - Update Changesets configuration to recognize both 1st-gen and 2nd-gen workspaces, enabling independent versioning strategies - Refactor release scripts to delegate to generation-specific publishing workflows rather than operating on a flat package structure - Update CI/CD publishing jobs to build, test, and publish both generations with appropriate dependency handling for the shared Core library - Preserve existing 1st-gen package publishing behavior to avoid disruption to current consumers This workflow enables continuous delivery of improvements to 1st-gen customers while supporting independent 2nd-gen package releases.

Why would we be deprecating S2-specific types? Did we mean S1-specific?

Great catch - I updated it too!

Description
This PR restructures the Spectrum Web Components repository into a dual-generation monorepo to support side-by-side development of 1st-gen and 2nd-gen components. This architectural change is foundational to the project's strategic objectives and enables the team to pursue multiple goals in parallel without disruption.
Key changes:
1st-gen/workspace, preserving all existing functionality2nd-gen/workspace with initial package structure for@spectrum-web-components/coreand@adobe/swc@spectrum-web-components/core) containing abstract, non-rendering base classes that both generations can extendMotivation and context
This change implements the "side-by-side development" strategy outlined in our project objectives, providing two critical advantages:
Isolation: 1st-gen and 2nd-gen workspaces are separated, allowing 2nd-gen to be built iteratively from the ground up without risking breakage to 1st-gen. Disruptive changes (tooling overhauls, Spectrum CSS unification, full-fidelity Spectrum 2 implementation) are confined to
2nd-gen/, while 1st-gen continues operating "as-is".Colocation: Both generations live in the same repository and share core component logic through abstract base classes in
@spectrum-web-components/core. This means:This architectural foundation enables the team to work efficiently on multiple strategic objectives in parallel:
