原问题

• App-owned storage path policy was split across store/shared_store.py, store/harness_support.py, and application/marketplace/cache.py, which left shared-store migration rules and marketplace cache rules inconsistent.
• Marketplace internals still carried dead cache/schema fields (githubFolderUrl, snapshot repoUrl) and old cache namespaces even though the runtime no longer needed those payload shapes.
• Docs and frontend tests had drifted from the current runtime contract, including stale managed-skills wording and repeated marketplace fixture payloads using old avatar semantics.

本次修复

• Added skill_manager/storage_paths.py as the single app-owned path policy module, moved shared-store resolution and harness settings path ownership there, and switched marketplace cache resolution to canonical app data only.
• Removed dead marketplace cache fields and snapshot metadata (githubFolderUrl, internal repo_url), bumped detail and repo-metadata cache namespaces to v2, and kept compatibility only for shared-store fallback plus Codex legacy discovery.
• Realigned README, managed-skills copy, and frontend/backend test fixtures to the current DTO/runtime contract, including a shared marketplace frontend fixture helper and dedicated storage-path unit coverage.
