[FEATURE] Make welcome screen layout consistent regardless of CLAUDE.md presence

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, Claude Code shows:

• A bordered, rich welcome screen (tips, recent activity) in directories WITHOUT CLAUDE.md
• A compact, minimal layout in directories WITH CLAUDE.md

This creates inconsistent UX depending on project state.

Suggestion:
Decouple UI layout from project initialization state.

Proposed Solution

Proposed solutions:

1. Add a config option (e.g. ui.layout = "boxed" | "compact")
2. Or allow a CLI flag (--ui boxed)
3. Or default to consistent layout and only conditionally show tips
