Bug Fix: TUI Navigation for Custom Preset + SDD

Fixed a navigation bug where selecting a SDD mode (single/multi) during custom preset installation would send the user back to the component selector instead of advancing to the next step.

What was wrong

In custom preset mode, the screen ordering is reversed compared to standard presets. The navigation logic didn't account for this in several screens, causing:

• SDD Mode screen: selecting "single" (or "multi" without cache) looped back to the component selector
• Model Picker: "Continue" after assigning models also went backwards
• Back buttons: enter-based "Back" and esc disagreed on where to go across multiple screens

What's fixed

• SDD Mode and Model Picker now correctly advance to Skill Picker or Review in custom preset
• All back-navigation paths (enter "Back" button + esc key) are now consistent across every screen for both custom and non-custom presets
• Skill selections are preserved when navigating back and forward through the flow
• Stale model assignments are properly cleared when re-entering the Model Picker

Scope

11 navigation fixes across confirmSelection() and goBack() in model.go, validated through 4 rounds of adversarial review covering 12 scenarios x 3 navigation paths each.

Documentation Alignment

Full audit of docs against the actual codebase:

• Removed false claim that coding skills (react-19, tailwind-4, etc.) are installed by gentle-ai — they live in Gentleman-Skills
• Fixed preset descriptions (Minimal was documented as "Engram+Persona+Permissions" but is actually Engram-only; Ecosystem Only listed wrong components)
• Removed 9 dead SkillID constants from model/types.go
• Fixed VSCode Copilot ConfigPath from ~/.github to ~/.copilot
• Updated architecture.md agent count from 5 to 8, added missing packages, removed Fedora from E2E claims
• Added Codex, Windsurf, Antigravity to Windows config paths table
