fix: address 12 code review findings for datamate manager PR

- Sanitize API error messages to avoid leaking response bodies
- Fix `getDatamate` N+1 fetch with single-item endpoint + fallback
- Add Zod validation for `IntegrationSummary` and `resolveIntegrations`
- Remove in-memory `activeDatamateServers` Set — use `MCP.status()` instead
- Export `slugify` and import in tests instead of duplicating
- Fix `handleDelete` to scan MCP status for matching servers, report results
- Fix `handleRemove` to default to project scope (not both scopes)
- Restore `McpRemoveCommand` (was dropped in PR)
- Restore non-interactive mode in `McpAddCommand` with CLI flags
- Remove dead re-export from `mcp.ts`
- Remove `@ts-nocheck` from test file
- Add `chmod 600` security note to altimate-setup skill
