[MEDIUM] PR #2 (70 files) should be split into smaller reviewable PRs

[0xbbjoker]

Summary

PR #2 contains 70 files spanning many domains (layouts, sidebar, dashboard, apps, containers, MCPs, agents, API explorer, misc). This is too large for effective code review.

Impact

• Reviewers will miss issues due to review fatigue
• Hard to isolate regressions to specific changes
• Merge conflicts more likely with such a large changeset
• Rollback is all-or-nothing

Recommended Split

PR	Contents	Files
PR #2a	Layout + Sidebar + Header + Dashboard Home	~19
PR #2b	Apps + App Builder + Containers + MCPs	~29
PR #2c	Agents + API Explorer + Misc UI	~22

This maintains the dependency chain (#1 → #2a → #2b/#2c) while making each PR manageable.
