Plan 14 (#2839) test listed only cli-code/cli-agents/acp-agents/cloud-agents; #2858 added agent-bridge/traffic-inspector to TOOLS_GROUP. Align test to real code (both feature sets).
- sidebarVisibility.ts: replace cli-tools with cli-code, add cli-agents, keep acp-agents order cli-code→cli-agents→acp-agents→cloud-agents in TOOLS_GROUP; update HIDEABLE_SIDEBAR_ITEM_IDS and DEVELOPER_SHOWN preset
- next.config.mjs: 4 permanent (308) redirects for /dashboard/cli-tools→/dashboard/cli-code and /dashboard/agents→/dashboard/acp-agents (with :path* wildcards)
- pt-BR.json + en.json: add cliCommon, cliCode, cliAgents, acpAgents namespaces (~140 keys each) + sidebar keys for the 3 new IDs
- request.ts: merge EN as namespace-level fallback so 39 non-EN/pt-BR locales display new namespaces in English until translations ship
- Header.tsx: update HEADER_DESCRIPTIONS map to use new HideableSidebarItemId values
- tests: 4 new unit test files (38 assertions), update sidebar-visibility.test.ts omni-proxy item order
