Redesign Lumos platform surfaces

[candasoz01-cmd]

Summary

• Reframes the home page from a chat-product landing into a Lumos platform/control-layer surface.
• Reorganizes /panel as a real workspace: modules, central chat, identity/system/task context.
• Adds desktop/mobile evidence, before/after comparisons, and two explored visual variants.

Scope

• Selected variant B: stronger ecosystem and orchestration signal while keeping the dark Lumos language, turquoise/gold accents, and restrained motion.
• Adds clear Lumos ID, security, AI orchestration, integrations, automation, developer, and device ecosystem messaging.
• Labels unavailable capabilities as roadmap/preparing instead of presenting them as live.
• Preserves existing routes, panel behavior, redirects, and release configuration.

Out of scope

• No production deployment.
• No OAuth secrets, environment values, or private OAuth implementation copied into this public branch.
• No backend/provider behavior changes.

Validation

• npm run build — 15 static routes built.
• targeted UI/i18n tests — 148 passed.
• full suite — 1320 passed, 3 skipped.
• npm run e2e:smoke --prefix ui — passed.
• merge simulation with cursor/oauth-callback-live-02d4 — clean, no conflicts.
• local mobile checks: home 375/375 and panel 390/390 client/scroll width; no horizontal overflow.

Visual review

Known risks

• Public main does not contain the production OAuth routes; this branch intentionally leaves that private integration boundary untouched.
• Some long legacy landing content remains in source and is visually de-emphasized; a later content-debt pass may remove it after product approval.
• npm install reports 5 existing audit findings (1 low, 1 moderate, 3 high); this PR does not broaden scope into dependency upgrades.
