feat(prospector): create @applications/@prospector/ skeleton with prospector-client and prospector-ui package skeletons (Wave 1 structure only)
- Per Quinn Prospector plan Wave 1 (independent): @applications/@prospector/ root + @packages/ sub structure.
- prospector-client/: Sources/ProspectorClient/ + Tests/ProspectorClientTests/ + Package.swift (product "ProspectorClient") + README.
- prospector-ui/: Sources/ProspectorUI/ + Tests/ProspectorUITests/ + Package.swift (product "ProspectorUI", depends on ../prospector-client) + README.
- Top-level placeholders: designs/, mcp/, docs/ + root README.md .
- All per task: basic skeletons, exact README migration note text, .gitkeep for dirs. No edits to old @quinn-prospector/ or @packages/@swift/@prospector/ sources.
- Verified pre-commit: list_dir + find + swift package describe (manifests valid; empty-target expected until migration in later wave).
- Git: scoped add only, on main, new repo no remote (commit local), pre-checked container git status clean for this change, no pollution per agent-cleanup.
- Follows Git Commit Protocol, safety-rules, zero tech debt, collective execution.
