Create sub-module 019.02 for richer project modeling

[Copilot]

This introduces 019.02 richer-project-modeling under 019_templates so upcoming work on richer project/module metadata has a dedicated place in the Ito module tree. It also replaces the default wildcard scope with concrete boundaries for the sub-module.

• New sub-module

  • Added 019.02 as a child of 019_templates
  • Creates a stable target for future changes related to richer project modeling

• Scoped module definition

  • Added a purpose focused on project/module metadata and scaffolding
  • Defined explicit scope areas instead of a placeholder catch-all

• Module layout

  • Uses the existing sub-module convention under .ito/modules/019_templates/sub/

# Richer Project Modeling

## Purpose
Richer project and module modeling for Ito project metadata and scaffolding

## Scope
- Project metadata structure and richer project-level modeling artifacts
- Module and sub-module modeling details exposed in generated templates
- Template scaffolding updates that guide users toward richer project modeling

Closing this as premature/stale module scaffolding. The PR only adds a new sub-module file, there are no active Ito changes targeting , and the branch/title drift suggests it is no longer being actively driven. We can recreate the sub-module when richer project-modeling work actually starts so the module tree stays aligned with real proposal/change work instead of placeholders.

Closing rationale: this PR only adds a new sub-module placeholder, there are no active Ito changes targeting 019.02 today, and the branch/title drift suggests it is no longer being actively driven. We can recreate this sub-module when richer project-modeling work actually starts so the module tree stays aligned with real proposal/change work instead of speculative scaffolding.
