Leo 6ee6fee8b9 chore: remove duplicate credentials/ dir + add CLAUDE.md + .claude rules
credentials/ was a leftover duplicate — all credential routes already live
in cypher-executor/src/routes/credentials.ts. Adds the SDD protocol,
tech-stack, forbidden-list, component-architecture, and progress rules
that guide Phase 1-6 refactors.
