Expose workspace files to source inventory

[chubes4]

Summary

• Add a Data Machine Code source inventory executor for kind=workspace_files.
• Register it on Data Machine's datamachine_source_inventory_page_callback and datamachine_source_aggregate_page_callback seams.
• Return stable source-file items from managed DMC workspace checkouts so Data Machine flows can inventory source files and upsert tracked-items coverage without custom downstream tasks.

Verification

• php -l inc/SourceInventory/WorkspaceSourceInventory.php
• homeboy test --path /Users/chubes/Developer/data-machine-code@fix-workspace-source-inventory --extension wordpress
• Deployed to wp-docs-runtime and executed datamachine/source-inventory against workspace handle wordpress-develop, path src/wp-includes/abilities-api; result found 4 source files and upserted 4 tracked items in namespace wp-docs:wordpress-core:abilities-api-pilot.
• vendor/bin/phpcs inc/SourceInventory/WorkspaceSourceInventory.php data-machine-code.php could not run locally because this repo worktree does not provide vendor/bin/phpcs.

AI assistance

• AI assistance: Yes
• Tool(s): OpenCode (GPT-5.5)
