Spectral v6 ships no implicit ruleset — the CI job exited 'no ruleset found'.
Adds .spectral.yaml (extends spectral:oas, documentation-only warnings relaxed
for design-time stubs), adds operation tags to the _example contract so it lints
clean (0 results), and aligns the api-contract-stub note.

Introduces the SDD root: a v1.0.0 constitution and machine-readable AGENTS.md
grounded in the project's real conventions; six EARS-aware persona spec-review
checklists that cross-reference .claude/personas/; feature-spec/ADR/threat-model/
api-contract templates; a fully worked _example feature; a living RTM; and an
adrs/ pointer that reuses the existing docs/adr/ archive.
