TASK-69	folk-rapp auto-derives space context + subdomain URL canonicalization	Done		2026-02-28 00:29	2026-02-28 00:29	fix routing canvas		high

Description

Two fixes ensuring rApps on canvas load as applets directly in the correct space:

1. folk-rapp race condition fix: createRenderRoot unconditionally read getAttribute("module-id") which returned "" and overwrote the moduleId already set via JS property setter — showing the picker menu instead of loading the module. Fixed to preserve JS-set properties.

2. Auto-derive spaceSlug: folk-rapp now reads the current URL path (/{space}/canvas → space) to auto-derive spaceSlug so embedded rApps always know their space context without explicit passing.

3. Subdomain canonicalization: rspace.online/{space}/{moduleId} now 301-redirects to {space}.rspace.online/{moduleId}. Spaces are subdomains, not path segments.

Acceptance Criteria

• #1 folk-rapp shapes with moduleId set load the iframe directly without showing picker
• #2 spaceSlug auto-derived from URL when not explicitly provided
• #3 rspace.online/{space}/{moduleId} redirects 301 to {space}.rspace.online/{moduleId}
• #4 newShapeElement passes communitySlug as fallback spaceSlug when restoring folk-rapp from sync
• #5 bun run build passes with zero errors

Final Summary

Fixed folk-rapp shapes to load as applets directly in the current space. Resolved race condition where createRenderRoot overwrote JS-set moduleId. Added auto-derivation of spaceSlug from URL. Added 301 redirect from path-based space URLs to subdomain form. Commits: 09d23f8, 9f3c9ab. Deployed to production.
