Summary

Remove dead UI code from the macOS native app that references gutted backend systems. After the middleware replacement (CLI agent runtimes via ChannelBridge), two features visible in the macOS app no longer have functioning backends:

1. Skills system — the gateway no longer implements skills.* RPC methods (gutted in PR feat: gut skills system and ClawHub (#63) #64). The macOS Settings tab and onboarding skills overview call dead endpoints.
2. LLM model catalog — the local ModelCatalogLoader reads models.generated.js from the old in-process LLM system (gutted in PR feat: remove in-process LLM packages and dead model management #108). The models.list gateway method exists in the method list but has no handler implementation.

The wizard/onboarding flow is ALIVE — wizard.* gateway methods are fully functional (redesigned in PR #90). Do NOT touch wizard UI code.

iOS and Android do NOT have skills settings or model catalog UI — this is macOS-only dead code.

Verification

Pre-check (understanding what's dead)

To verify skills methods are dead:

# Gateway method list — no skills.* methods
grep 'skills' src/gateway/server-methods-list.ts
# Expected: no output

# Gateway handlers — no skills handler
grep 'skills' src/gateway/server-methods.ts
# Expected: no output

To verify model catalog handler is dead:

# models.list exists in method list but has no handler
grep 'models' src/gateway/server-methods.ts
# Expected: no output (no handler imported or registered)

Post-change verification

# macOS app builds successfully
cd apps/macos && swift build

# No references to deleted views remain
grep -rn 'SkillsSettings\|SkillsModels\|ModelCatalogLoader' apps/macos/Sources/ --include='*.swift'
# Expected: no output

# Skills methods removed from GatewayConnection
grep -n 'skillsStatus\|skillsInstall\|skillsUpdate' apps/macos/Sources/OpenClaw/GatewayConnection.swift
# Expected: no output

# Model catalog constants removed
grep -n 'modelCatalogPathKey\|modelCatalogReloadKey' apps/macos/Sources/OpenClaw/Constants.swift
# Expected: no output

Acceptance Criteria

• SkillsSettings.swift, SkillsModels.swift, SkillsSettingsSmokeTests.swift deleted
• ModelCatalogLoader.swift, ModelCatalogLoaderTests.swift deleted
• Skills tab removed from SettingsRootView.swift
• Skills overview removed from onboarding readyPage()
• Skills methods removed from GatewayConnection.swift
• Skills reference removed from ExecApprovals.swift
• Model catalog section removed from DebugSettings.swift
• Model catalog constants removed from Constants.swift
• cd apps/macos && swift build passes
• grep confirms zero references to deleted types/files in remaining app code

Scope

~5 files deleted, ~5 files modified. macOS only. iOS and Android have no dead skills/model-catalog UI.
