Summary
Add Grok 4.5 as a selectable model in OpenClaw's bundled xAI provider.
Problem to solve
xAI released grok-4.5, but OpenClaw's bundled xAI catalog does not publish its current model metadata or aliases. Users cannot select it through normal xAI setup/model discovery, and the default live-model matrix still exercises Grok 4.3.
Proposed solution
Add grok-4.5 with its published 500k context window, text/image input, token pricing, prompt-cache pricing, and low/medium/high reasoning contract. Normalize the official grok-4.5-latest and grok-build-latest aliases, document the model, and move the high-signal xAI live lane to Grok 4.5.
Keep Grok 4.3 as the regional-safe setup default while xAI's launch documentation says Grok 4.5 is unavailable to EU API-console users.
Alternatives considered
Making Grok 4.5 the unconditional setup default would break fresh EU API-key setups today. Discovery-only publication would also leave static/offline catalogs and alias normalization incomplete.
Impact
Affected: xAI API-key and OAuth users who want the current frontier model.
Severity: Medium; existing Grok models continue working, but Grok 4.5 cannot be selected reliably without first-class metadata.
Frequency: Every Grok 4.5 selection or setup attempt.
Consequence: Manual provider overrides, incorrect context/cost display, or unknown-model failures for official aliases.
Evidence/examples
Additional information
The change is additive. Existing Grok 4.3, Grok Build 0.1, and Grok 4.20 selections remain available.
