Added collection‑level suggestion, rule, and embed iteration features.

Full changelog

feat(presenter): Collection-Level Suggestions, Rules, and Embed Iteration

Added

*\collectionSuggestActions()\ / \collectionSuggest()* — HATEOAS-style action suggestions at the collection level. Callback receives the full \T[]\ array, enabling aggregate suggestions (batch operations, bulk approvals).
*\collectionRules()* — collection-level system rules evaluated with the entire validated array. Supports static \string[]\ or dynamic (items[], ctx?) => (string | null)[].
\definePresenter()\ config fields — \collectionSuggestions\ and \collectionRules\ for the declarative API.
25 new tests — edge cases including empty arrays, context forwarding, agentLimit combo, deduplication.

Fixed

*_attachSuggestions()* evaluated only the first array item — now uses \collectionSuggestActions\ when configured.
*_attachRules()* dynamic rules evaluated only first item — new \collectionRules\ provides aggregate-level rules.
*_processEmbeds()* processed only first array item — now iterates all items with rule dedup via \Set.
