🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR adds ADR 0032 proposing the decomposition of the server Core project into feature-scoped libraries. The document follows the established ADR structure (Context, Considered options, Decision outcome, consequences, Plan), uses frontmatter consistent with ADR 0031, and is auto-registered via the DocCardList index. The bitwarden_license layout example requested in the existing review thread has been added.

Code Review Details

No findings. This is a documentation-only change (a single prose ADR). The file naming, frontmatter, cross-references to ADR 0031, and directory placement all match repository conventions. The illustrative C# examples are syntactically valid, and the prior reviewer feedback about a bitwarden_license example has been addressed.

One minor but important adjustment. Dealers choice on how to implement said change.
