Completes the Phase 5 follow-up: rules now get the same update-over-create
gate. Title-based only (rules aren't a semantic-retrieval/RAG surface), scoped
to the same topic (rulebook rule) or same project (project rule). force=true
overrides; fail-open like the note/task gate.
Deferred-item decisions (operator): REST/web gating SKIPPED (kept MCP-only —
humans rarely double-create and a hard block needs UI affordance); orphan scope
kept orphan↔orphan (no change). So this rule gate is the only remaining build.
- services/dedup.py: find_duplicate_rule(title, topic_id|project_id).
- create_rule + create_project_rule: force param + gate.
- tests: rule title match, scope-required guard, tool gate (block + force).
