[Change] Package bundle-owned prompts and resource payloads with official bundles

[djm81]

Summary

Bundle-owned prompt templates and other module-owned resources are still stored in the core CLI repo while the official bundle packages ship without those assets. This issue tracks moving those resources into the owning bundle packages and making bundle integrity/version-bump flows resource-aware.

This issue does not own the specfact-cli runtime discovery, source selection, or specfact init ide export orchestration. That core-side work is tracked separately in nold-ai/specfact-cli#382 (init-ide-prompt-source-selection).

Scope

• package workflow prompt templates inside the owning official bundles
• package backlog field mapping templates and other audited module-owned resources inside the owning bundles
• preserve stable bundle resource paths for specfact-cli discovery
• verify signing, verification, and version-bump enforcement detect resource-only changes
• explicitly leave specfact-cli runtime selection/export behavior out of scope here; this repo provides payloads, while core consumes them

Cross-Repo Boundary

• specfact-cli-modules #101 owns the packaged payloads and stable bundle resource layout
• specfact-cli packaging change packaging-02-cross-platform-runtime-and-module-resources owns the consuming installed-resource contract
• specfact-cli #382 owns runtime source selection, specfact init ide orchestration, and user/project/custom root export behavior

OpenSpec

• Change: packaging-01-bundle-resource-payloads
• Repo path: openspec/changes/packaging-01-bundle-resource-payloads/
• Cross-reference: nold-ai/specfact-cli#382 for the narrowed core-side orchestration scope
