…esponse LLMs only see the 'content' text field in MCP tool results, not the 'structured_content' field. This change includes human-readable format details in the text content so Claude and other LLMs can see: - Format name and ID - Type and dimensions - Supported macros (full list) - Assets required - Description The structured_content still contains the full JSON for programmatic use. Extracted _format_to_human_readable() helper function for reusability.
IMPRESSION_URL is not part of the universal macros specification.

- Replace manual assets_required iteration with get_format_assets() and get_required_assets() - Utilities handle both new 'assets' and deprecated 'assets_required' fields automatically

Summary
This PR upgrades the adcp-client-python dependency to 2.18.0 and enhances the list_creative_formats tool to provide better human-readable output for LLM consumption.
Changes
1. Enhanced list_creative_formats Response
Added human-readable format details in the tool response content field
Each format now displays: name, ID, type, dimensions, description, required assets, optional assets, and supported macros
LLMs can now see full format specifications without needing structured data parsing
2. Upgraded to adcp-client-python 2.18.0
Updated dependency from adcp>=2.13.0 to adcp>=2.18.0
Migrated to new assets field (replaces deprecated assets_required)
Added create_asset() helper function returning the new Assets type
Backfill assets_required from assets for backward compatibility using get_required_assets() utility
3. Added Optional Impression Tracker Asset
Added create_impression_tracker_asset() helper for 3rd party tracking pixels
All formats (except VAST) now include an optional impression_tracker asset
VAST formats excluded as they have built-in tracking in the XML
4. Updated Server Utilities
_format_to_human_readable() now uses get_required_assets() and get_optional_assets() from adcp
Properly distinguishes between required and optional assets in output
5. Test Updates
Updated tests for PreviewRender which is now a RootModel (access via .root)
Updated tests for relaxed schema validation (additional fields now allowed)
Updated test_info_card_formats.py to verify new assets/assets_required structure
6. Bug Fix
Removed IMPRESSION_URL from COMMON_MACROS (not a universal macro)
Testing
All 256 tests pass ✅
Lint checks pass ✅
1. Test new assets discovery
2. Test improvement on LLM response
