Bug Description

The TUI /model picker displays all 296 models from every provider, instead of showing only the models the user has configured in their openclaw.json.

Screenshot

User has ~6 models configured in agents.defaults.models and custom providers. When they type /model and search for 'kimi', they get 9+ Kimi variants from providers they don't have set up, making it nearly impossible to find the one they actually configured (kimi-coding/k2p5).

The counter shows 1/296 — 296 models for a user with 6 configured.

Expected Behavior

The model picker should default to showing only models the user has configured in:

• agents.defaults.models
• models.providers[].models[]
• Or models with active API keys/auth

There should be an option to browse all available models (e.g., a toggle or separate command), but the default picker should show only configured/active models.

Why This Matters

1. User configured kimi-coding/k2p5 but the picker shows 9 Kimi variants, most of which won't work because they're not set up
2. Selecting an unconfigured model gives a cryptic model not allowed error
3. Users can't remember the exact model slug among hundreds of similar names
4. The search helps but doesn't solve the core problem — too much noise, not enough signal

Suggested Fix

• Add a config option like models.pickerMode: "configured" | "all" (default: configured)
• Or split into two commands: /model (configured only) and /model-browse (all available)
• Show a visual indicator (star, checkmark) next to configured models when browsing all
• Show aliases prominently (e.g., 'Kimi Code' instead of just 'kimi-coding/k2p5')

Environment

• OpenClaw TUI
• macOS
• User has custom kimi-coding provider + openrouter configured in openclaw.json
