Add comprehensive implementation plan for v3.7.0 refactor that
separates Codex MCP configuration from unified MCP structure.
Key design decisions:
- Codex MCP stored as raw TOML string in codexMcp.rawToml
- Unified MCP (mcp.servers) only supports Claude/Gemini
- Complete isolation: no apps.codex in unified structure
- Migration clears mcp.codex.servers to prevent pollution
Architecture improvements:
- Single responsibility: each data source has one purpose
- No priority conflicts: completely independent data paths
- Simplified switching logic: no conditional branches
- UI constraints: Tab1 limited to claude/gemini only
Implementation phases:
- Phase 0: Setup (0.5d)
- Phase 1: Backend foundation (1.5d)
- Phase 2: Command layer (1d)
- Phase 3: Switching logic (1d)
- Phase 4: Frontend API (0.5d)
- Phase 5: UI implementation (2d)
- Phase 6: Enhancements (1d, optional)
- Phase 7: Testing & docs (1d)
Total: 8.5 days (MVP: 7 days)
Addresses TOML-JSON conversion data loss issue by preserving
raw TOML format for Codex while maintaining structured approach
for Claude/Gemini.
