Oleg Isonen 03aeb535ef feat: Add semantic Collection authoring to MCP (#5880) ...

## What changed

- Add an `insert-collection` MCP and CLI operation for creating repeated
UI from array or object data.
- Create the Collection, iterable binding, current-item/current-key
parameters, repeated item structure, and descendant bindings atomically.
- Accept literal JSON data or expressions backed by project variables
and resource results.
- Support `collectionItem` and `collectionItemKey` expressions inside
the repeated Webstudio JSX item.
- Return the created Collection, item root, and parameter IDs for
immediate inspection and follow-up edits.
- Document when agents should use Collection for lists, grids, cards,
rows, options, tabs, and other repeated content.

## Why

Building a data-driven list previously required several low-level
operations and manual handling of Collection's internal parameters. A
missed step could leave a partially configured or incorrectly scoped
Collection.

## User impact

Agents can turn resource or variable data into a correctly bound
repeated layout in one operation, then inspect and refine the result
normally.

## Validation

- Real-world local CLI test created and rendered a three-product
Collection from project data.
- Tests cover literal arrays, objects, resource expressions, item/key
bindings, malformed fragments, ID conflicts, server execution, and
project-session behavior.
- 176 focused tests, project-build typecheck, and generated-doc checks
pass after rebasing onto current `main`.
