fix(providers): make all models available in kilocode provider (#32352)

* kilocode: dynamic model discovery, kilo/auto default, cooldown exemption

- Replace 9-model hardcoded catalog with dynamic discovery from
  GET /api/gateway/models (Venice-like pattern with static fallback)
- Default model changed from anthropic/claude-opus-4.6 to kilo/auto
  (smart routing model)
- Add createKilocodeWrapper for X-KILOCODE-FEATURE header injection
  and reasoning.effort handling (skip for kilo/auto)
- Add kilocode to cooldown-exempt providers (proxy like OpenRouter)
- Keep sync buildKilocodeProvider for onboarding, add async
  buildKilocodeProviderWithDiscovery for implicit provider resolution
- Per-token gateway pricing converted to per-1M-token for cost fields

* kilocode: skip reasoning injection for x-ai models, harden discovery loop

* fix(kilocode): keep valid discovered duplicates (openclaw#32352, thanks @pandemicsyn)

* refactor(proxy): normalize reasoning payload guards (openclaw#32352, thanks @pandemicsyn)

* chore(changelog): note kilocode hardening (openclaw#32352, thanks @pandemicsyn and @vincentkoc)

* chore(changelog): fix kilocode note format (openclaw#32352, thanks @pandemicsyn and @vincentkoc)

* test(kilocode): support auto-model override cases (openclaw#32352, thanks @pandemicsyn)

* Update CHANGELOG.md

-## Surfaced model refs
+## Default model
 
-The built-in Kilo Gateway catalog currently surfaces these model refs:
+The default model is `kilocode/kilo/auto`, a smart routing model that automatically selects
+the best underlying model based on the task:
 
-- `kilocode/anthropic/claude-opus-4.6` (default)
-- `kilocode/z-ai/glm-5:free`
-- `kilocode/minimax/minimax-m2.5:free`
-- `kilocode/anthropic/claude-sonnet-4.5`
-- `kilocode/openai/gpt-5.2`
-- `kilocode/google/gemini-3-pro-preview`
-- `kilocode/google/gemini-3-flash-preview`
-- `kilocode/x-ai/grok-code-fast-1`
-- `kilocode/moonshotai/kimi-k2.5`
+- Planning, debugging, and orchestration tasks route to Claude Opus
+- Code writing and exploration tasks route to Claude Sonnet
+
+## Available models
+
+OpenClaw dynamically discovers available models from the Kilo Gateway at startup. Use
+`/models kilocode` to see the full list of models available with your account.
+
+Any model available on the gateway can be used with the `kilocode/` prefix:
+
+```
+kilocode/kilo/auto              (default - smart routing)
+kilocode/anthropic/claude-sonnet-4
+kilocode/openai/gpt-5.2
+kilocode/google/gemini-3-pro-preview
+...and many more
+```
 
 ## Notes
 
-- Model refs are `kilocode/<provider>/<model>` (e.g., `kilocode/anthropic/claude-opus-4.6`).
-- Default model: `kilocode/anthropic/claude-opus-4.6`
+- Model refs are `kilocode/<model-id>` (e.g., `kilocode/anthropic/claude-sonnet-4`).
+- Default model: `kilocode/kilo/auto`
 - Base URL: `https://api.kilo.ai/api/gateway/`
 - For more model/provider options, see [/concepts/model-providers](/concepts/model-providers).
 - Kilo Gateway uses a Bearer token with your API key under the hood.
