release: FluencyLoop 0.3.18

[baokhang83]

Summary

• Measure the rendered gap between an embedded SVG title and its first diagram element.
• Require a 32-pixel title gap and measured per-line node-label clearance.
• Prevent planning documents from appearing as realized_by implementation evidence.
• Require implementing features to append updated concept records with concrete source paths.
• Release FluencyLoop 0.3.18 through the generated plugin manifests.

Verification

• bats tests/*.bats
• bash .github/scripts/bump-version.sh --check
• git diff --check

Reviewer note

The store remains append-only. When code replaces a plan-era concept, the newer record retains the
same name and names every real project-relative source path that realizes it; the reader then shows
that newer evidence.
