Use any name for your procedure YAML file

Your procedure file no longer has to be named procedure.yaml. Point your deployment's entry point at any YAML file and TofuPilot runs it.

• Added support for custom-named procedure YAML files (any .yaml/.yml) via the deployment entry point.
• Improved repository import so a custom-named procedure is detected and offered in the picker instead of being reported as missing.
• Fixed monorepo builds so a sibling procedure with a custom-named YAML ships as source instead of being skipped.
