A block field reads its node's children with a nested model

Acceptance Criteria

A block field accepts model, and still matches the whole node (D2.1)
Its members resolve to dotted names (quote.attribution), to any depth
A composition places a member by its dotted name or the whole node by the field's name, not both (D2.2)
An unmatched child inside the node is reported content-unmatched, naming the field (D2.4)
A nested model on a non-block field is rejected at load, and the composed-runes guide documents nested models

What was done

packages/types/src/content-model.ts: ContentFieldDefinition.model (a SequenceModel).
packages/runes/src/lib/resolver.ts:
- takeField resolves a non-greedy block match's children with its nested model into name.member keys (deeper levels are already dotted);
- dropped children are recorded per sink with the field path, and findUnmatchedContent publishes them for unmatchedInsideField.
packages/runes/src/lib/index.ts: content-unmatched names the nested model's field.
packages/runes/src/lib/composition.ts:
- the model key, parsed with parseContentModel, sequence only, block fields only (content-nested-invalid);
- slotFields adds dotted members;
- the placement rule: whole or every member, never both (nested-placed-twice), with partial member placement reported through field-unplaced.
packages/runes/test/content-model-nested.test.ts; the composed-runes guide section and error rows.
