Deferred-body capture for per-entity templates

Implement the deferBody mechanism SPEC-070's prototype validated: a catalog flag plus a pre-transform pass in the content loader that captures a rune's pristine body as a source string and empties it, so postProcess can re-parse and transform it per entity with a bound variable. Capture must happen before the page transform — by schema-transform time Markdoc has already resolved the body's $item interpolations to undefined.

Acceptance Criteria

  • A deferBody flag on a rune's catalog entry marks its body for deferred capture
  • A pre-transform loader pass walks the parsed AST and, for each deferBody rune, formats its children to source (Markdoc.format on pristine nodes), stashes it on an attribute, and empties the body so the page transform never resolves $item
  • postProcess re-parses the stashed source and transforms it per entity with the bound variable; reparse-per-entity is used (reusing captured AST resolves variables to null)
  • The mechanism is generic — used by collection body templates (WORK-263) and table column cells (WORK-264)
  • Tests confirm independent, correct per-entity output across N entities

Dependencies

None — foundation. Pairs with WORK-263 (collection) which is the first consumer.
