…chema sanitization, model filtering - Fix DEFAULT_BASE_URLS: add daily-cloudcode-pa.googleapis.com as primary endpoint - Fix sdkMode 'openai' → 'anthropic' to route through AntigravityStreamProcessor - Add StreamingStartedError to prevent endpoint-retry after streaming starts (avoids tool call duplication) - Expand GEMINI_UNSUPPORTED_FIELDS: add const, enumDescriptions, default, format, cache_control and 6 more - Fix fetchModels/getCachedModels: filter models by API quota response; fall back to all on empty - Fix setApiKey ordering: persist filtered model list before account-change event fires (both new and existing account paths) - Fix thinkingTagBuffer: flush remainder at stream end to avoid losing trailing response - Add totalTextEmitted counter: if stream ends with zero text but non-empty thinking, emit thinking as text (fixes GPT OSS 120B thought-only responses) - Remove auto-add-to-compatible on login - Update DEFAULT_USER_AGENT to antigravity/1.22.2 - Update model aliases: Gemini 3.1 naming, claude-opus-4-6-thinking, gpt-oss-120b-medium - Add claude-opus-4-6-thinking to antigravity.json; translate tooltip fields to English - Bump version 0.15.27 → 0.16.0

Summary
Complete fix for the Antigravity (Google Cloud Code) provider. All issues discovered during live testing have been resolved.
Changes
Network / Routing
DEFAULT_BASE_URLS: Addeddaily-cloudcode-pa.googleapis.comas the primary endpoint — the old list only had sandbox and legacy URLs, causing 404 on all requestsDEFAULT_USER_AGENTtoantigravity/1.22.2Stream Processing
sdkMode: Changed from'openai'to'anthropic'so requests route toAntigravityStreamProcessorinstead ofOpenAIStreamProcessor(which couldn't parse the Gemini-format SSE stream — no output was produced)StreamingStartedError: Prevents endpoint-fallback retry after streaming has already started, which would replay tool calls and produce duplicates in the Copilot UIthinkingTagBufferflush: The tag lookahead buffer could hold up to 10 chars past end of stream; now flushed in thefinallyblock before final text flushtotalTextEmittedcounter + thought-only fallback: If the stream ends with zero text emitted but accumulated thinking content (e.g. GPT OSS 120B which returns 100%thought:trueparts), the thinking content is emitted as a text response instead of showing "Sorry, no response was returned"JSON Schema Sanitization
GEMINI_UNSUPPORTED_FIELDSin bothhandler.tsandrequestHelpers.ts: addedconst,enumDescriptions,enumCaseInsensitive,enumNormalizeWhitespace,default,deprecated,readOnly,writeOnly,format,cache_control,propertyNames— all sourced from anti-api's json-schema-cleaner; these cause HTTP 400 from the Gemini APIModel Filtering
fetchModels/getCachedModels: Models are now filtered to only those returned by the quota API endpoint — unavailable models are hidden. Falls back to full list if the API returns an empty responsetryFetchQuotaFromEndpoint: Tracks all models present in the response (not just those with explicitquotaInfo) — presence alone indicates availabilitysetApiKeyordering for both new-account and credential-refresh paths: API key (with filtered model list) is now persisted before the account-change event fires, soprovideLanguageModelChatInformationalready sees the correct model listaddAllAntigravityModelsToCompatiblecall on login — models are no longer auto-added to the Compatible ProviderConfig & Aliases
