Phase 1: Housekeeping + Configurable Attributes

[DavidLambauer]

Summary

• Fixes Improve composer dependencies #22: Added explicit Magento module dependencies (magento/framework, magento/module-catalog, magento/module-ui, magento/module-backend, magento/module-config, magento/module-store), removed mirror repository from composer.json
• Fixes Fix code style issues #23: Applied PSR-12 code style fixes across all PHP files via PHP-CS-Fixer
• Fixes Incorrect 'temperature' setting label #25: Corrected temperature field label (was "System Prompt"), added range/description comments to all advanced config fields, fixed duplicate sortOrder on presence_penalty
• Fixes Feature: Make attributes configurable #27: Replaced the hardcoded 5-attribute enrichment system with a dynamic row configuration — any text/textarea product attribute can now be enriched without code changes

Configurable Attributes (#27) Details

The static textarea fields for short_description, description, meta_title, meta_keyword, and meta_description have been replaced with a dynamic rows table in the admin config (Stores > Configuration > Catalog > AI Data Enrichment > Product Fields Auto-Generation).

Each row has:

• Attribute — dropdown populated from product text/textarea attributes
• Prompt — the prompt template with {{variable}} support
• Enabled — toggle per attribute

Changes:

• Block/Adminhtml/Form/Field/AttributeColumn — select renderer loading product text/textarea attributes via ProductAttributeRepositoryInterface
• Block/Adminhtml/Form/Field/ProductAttributes — dynamic rows field array block extending AbstractFieldArray
• Model/Config — new getEnrichableAttributes() method reads the serialized dynamic rows; getProductPrompt() delegates to it
• Model/Product/Enricher — getAttributes() now reads from config instead of returning a hardcoded array
• Setup/Patch/Data/MigrateProductPromptsToDynamicRows — data patch migrating existing per-attribute config values to the new serialized format, then cleans up old paths
• Default prompts added for meta_title, meta_keyword, and meta_description (previously had no defaults)

Test plan

• Run setup:upgrade — should complete without errors
• Run setup:di:compile — should complete without errors
• Verify dynamic rows table renders at Stores > Config > Catalog > AI Data Enrichment > Product Fields Auto-Generation
• Verify attribute dropdown loads product text/textarea attributes
• Add a custom attribute row, save config, reload — confirm persistence
• Verify enrichment still works: create a new product with the module enabled
• Verify mass actions still work from the product grid
• For existing installs: confirm data patch migrates old prompt config values correctly

Closing in favor of @rhoerr's standalone PRs that cover the same issues with less bundling: #39 (#22), #38 (#25), #45 (#27).

The only piece not covered by Ryan's stack is #23 (PSR-12 code style). I'll open a separate small PR for that on top of the merged baseline so it doesn't get held up by the bigger overlap.
