- Run cargo fmt on all Rust crates for consistent formatting
- Update CLAUDE.md with WASM plugin commands and dev.ps1 instructions
- Update wiki: add WASM plugin architecture, rewrite dev environment docs
- Minor frontend cleanup (unused imports)
Add VersionMismatch error variant and check_version() helper to erp-core.
All 13 mutable entities now enforce version checking on update/delete:
- erp-auth: user, role, organization, department, position
- erp-config: dictionary, dictionary_item, menu, setting, numbering_rule
- erp-workflow: process_definition, process_instance, task
- erp-message: message, message_subscription
Update DTOs to expose version in responses and require version in update
requests. HTTP 409 Conflict returned on version mismatch.
- Add POST /config/menus (create single menu)
- Add PUT /config/menus/{id} (update single menu)
- Add DELETE /config/menus/{id} (soft delete single menu)
- Frontend MenuConfig was calling individual CRUD routes that didn't exist,
causing 404 errors on all create/update/delete operations
- Fix frontend to correctly handle nested tree response from backend
