Add "Salesforce Object Metadata" action

Get Salesforce Object Metadata action implemented and committed.

What it does: Retrieve comprehensive metadata about any Salesforce object type including field definitions, properties, relationships, and capabilities. Built with performance optimization to handle large objects efficiently.

Key features:

• Complete object metadata retrieval using Salesforce objectDescribe API
• Performance-optimized field filtering system with smart defaults
• Configurable inclusion/exclusion of field types (address, geocode, system fields)
• Optional picklist value retrieval with memory usage warnings
• Field categorization (required, updateable, createable, relationships)
• Record type information and object capabilities

Available tokens:

• Object info: [token:object_type], [token:label], [token:key_prefix]
• Capabilities: [token:is_createable], [token:is_updateable], [token:is_deletable]
• Field data: [token:field_count], [token:field_names], [token:required_fields]
• Field details: [token:fields:Email:type], [token:fields:Email:label], [token:fields:Email:required]
• Picklists: [token:picklist_fields:Status], [token:picklist_fields:Status:New:label]
• Relationships: [token:relationship_fields:AccountId:references]

Performance options:

• Include picklist values: Default OFF - prevents massive country/state data bloat
• Include address fields: Default OFF - excludes Street, City, State, Country fields
• Include geocode fields: Default OFF - excludes Latitude, Longitude fields
• Include system fields: Default OFF - excludes CreatedDate, ModifiedDate audit fields
• Include relationship fields: Default ON - includes AccountId, OwnerId lookup fields

Testing: Successfully tested with Contact object. Reduced from 65 fields to 31 fields (52% reduction) with default filtering. Eliminated 100K+ character data bloat. All token access confirmed working.

Files added/changed:

• src/Plugin/Action/SalesforceObjectMetadata.php (new action)
• config/schema/salesforce_eca.schema.yml (configuration schema)

This completes the final roadmap item for v1.0.0. All planned features are now implemented and performance optimized.
