fix: improve NewAPI routing and capability overlays

[yyhhyyyyyy]

• Fix NewAPI endpoint selection when supported_endpoint_types is empty or stale by using owned_by, model family, and Provider DB hints for Anthropic/Gemini fallback inference.
• Separate NewAPI request endpoint routing from Provider DB capability ownership, so OpenAI-compatible models can still use vendor-specific capability metadata.
• Preserve owned_by as ownedBy model metadata and persist inferred endpointType / ownedBy in provider-managed model config.
• Improve capability overlays for AI SDK routes and NewAPI models, including reasoning, temperature, vision, and function-call metadata.
• Refresh Provider DB / ACP registry assets and add coverage for route inference, capability matching, and UI capability controls.

Summary by CodeRabbit

• New Features

  • Added Grok Build agent support to the registry.

• Improvements

  • Updated registered agent versions and distribution references across multiple platforms.
  • Enhanced temperature and top-P parameter controls to intelligently respect model capabilities.
  • Improved model capability detection and matching logic across providers.
  • Added model ownership metadata tracking for better model identification.

📝 Walkthrough

Walkthrough

This PR adds model ownership metadata (ownedBy) throughout the system and refactors model capability matching for better provider/model-id resolution. These improvements enable New API routing to infer endpoint types from ownership hints and gate sampling controls (topP) based on capability support. Agent registry entries are updated with version bumps and a new grok-build entry is added.

Changes

Model ownership and capability-aware routing

Layer / File(s)	Summary
Type contracts and schema foundations src/shared/types/presenters/legacy.presenters.d.ts, src/shared/types/presenters/llmprovider.presenter.d.ts, src/shared/contracts/common.ts, src/shared/contracts/domainSchemas.ts	Added optional ownedBy?: string field to ModelConfig, RENDERER_MODEL_META, MODEL_META, and ProviderModelSummarySchema to track model ownership across type definitions and validation schemas.
Ownership metadata propagation src/main/presenter/configPresenter/modelConfig.ts, src/main/presenter/configPresenter/providerModelHelper.ts, src/main/presenter/configPresenter/index.ts, src/main/presenter/llmProviderPresenter/managers/modelManager.ts, src/renderer/src/stores/modelStore.ts	Propagate ownedBy from model configs through config presenters, provider helpers, and renderer store; normalize and merge ownership metadata at model resolution points.
Model capability matching refactor src/main/presenter/configPresenter/modelCapabilities.ts, test/main/presenter/configPresenter/modelCapabilities.test.ts	Refactor capability matching to normalize provider/model identifiers and build a canonical modelLookupIndex for faster cross-provider resolution. Add three new public APIs: getCapabilityModel, getCapabilityModelMatch, and findCapabilityModelMatch. Change temperature-support fallback to default true instead of Claude-Opus-specific logic.
New API endpoint inference and model metadata src/shared/model.ts, src/main/presenter/llmProviderPresenter/providers/aiSdkProvider.ts, test/main/shared/model.test.ts, test/main/presenter/llmProviderPresenter/newApiProvider.test.ts	Extend NewApiRouteMeta with ownedBy and capabilityProviderId fields. Add helpers to infer special endpoint types (anthropic/gemini) from ownership and resolve runtime capability provider IDs. Parse owned_by from models and enrich metadata with capability-derived properties (vision, reasoning, function-call); group models by ownership.
Runtime sampling control (topP) src/main/presenter/llmProviderPresenter/aiSdk/runtime.ts, src/renderer/src/components/chat/ChatStatusBar.vue, src/renderer/src/components/settings/ModelConfigDialog.vue, test/main/presenter/llmProviderPresenter/aiSdkRuntime.test.ts, test/renderer/components/ChatStatusBar.test.ts, test/renderer/components/ModelConfigDialog.test.ts	Conditionally resolve topP at runtime based on provider capability (Anthropic reuses temperature-control check). Update runAiSdkGenerateText and streaming paths to omit topP when unsupported. Add supportsTopPControl and showTopPControl computed properties to Vue components to conditionally gate topP UI controls.

Agent registry maintenance

Layer / File(s)	Summary
Agent version bumps and distributions resources/acp-registry/registry.json	Update version numbers and platform-specific binary archive URLs or npx/uvx package references for 20+ registered agents (Amp, Auggie CLI, Claude Agent, Cline, Codebuddy Code, Codex CLI, crow-cli, DimCode, Factory Droid, fast-agent, Gemini CLI, GitHub Copilot, Goose, Kilo, Kimi CLI, Mistral Vibe, Nova, OpenCode, Poolside, Qwen Code, siGit Code).
New grok-build agent entry resources/acp-registry/registry.json	Register a new grok-build ("Grok Build") agent with version, description, authors, and platform-specific binary distribution configuration plus icon.

Poem

🐰 With whiskers twitching at metadata's bloom,
We hop through the ownedBy rooms,
Where capabilities match and topP takes flight—
New API routes glow anthropic-bright,
And Grok builds hop into the registry's night! ✨
