Syncs the fxtr plugin to 0.1.3:

• Document linked detail views and pages, typed view parameters, and entity links that follow their parent view.
• Refresh table and multi-invocation view guidance; deprecate singleInvocation and describe the viewer's panel layout.
• Ask experiments to keep EXPERIMENT.md current, and document validation when storing dataclass entities.
• Keep the existing fxtr, behaviors, and first-experiment skills.

Generated by pnpm sync:plugin from TransluceAI/fxtr3 main at c3782b93.

The sync leaves unchanged skills with their previous provenance. Their metadata was regenerated with scripts/skills/prepare.mjs from the same clean revision so all three skills describe one source revision. Both marketplace skill trees match the complete prepared bundle exactly.

Validation: all 22 skill/preparation tests passed; both marketplaces' checks and git diff --check passed. Changes are limited to the fxtr plugin and its marketplace version; other plugins are unchanged.

Hold merging until fxtr 0.1.0a0 and behaviors 0.0.1a4 are published from the package release PR. The source checkout still records the previous unpublished package versions, so refresh provenance from the final clean release revision before merge. The release requester explicitly waived the failing newest-dependency gate for this release; the normal locked-dependency release checks still apply.
