- Replace stale model IDs (gemini-3.1-pro-preview, gemini-3.1-flash-lite-preview)
with correct High/Low tier variants from fetchAvailableModels API
(gemini-3-pro-high, gemini-3-pro-low, gemini-3.1-pro-high, gemini-3.1-pro-low, etc.)
- Remove ag/ alias prefix in favor of antigravity/ across registry, providers,
model capabilities, combos, docs, and static model providers
- Make provider alias optional in Zod schema and guard ALIAS_TO_ID/ID_TO_ALIAS maps
- Show raw model IDs in quota display instead of unmapped display names
- Update T28 model catalog test to assert new High/Low tier models
- Add missing glm-4.7-flashx variant to provider registry (confirmed in
Z.AI official GLM-4.7 overview docs as one of three variants)
- Remove glm-4.7/glm4.7 from tool calling denylist — official docs
explicitly show GLM-4.7 supporting function calling with tools param
- Add estimated pricing for glm-4.7-flashx ($0.3/$1.1) between free
Flash and standard 4.7 tiers

Models like antigravity/claude-sonnet-4-6 route through Google's internal
Cloud Code API which returns HTTP 400 when thinking/reasoning parameters
are included in the request body.
Changes:
- open-sse/services/modelCapabilities.ts: add supportsReasoning() function
with a denylist of known-unsupported patterns (antigravity/claude-sonnet-*)
and a registry-based lookup hook (supportsReasoning flag per model)
- open-sse/services/thinkingBudget.ts: in applyThinkingBudget(), add early
exit before the mode switch — if model string is present and
supportsReasoning() returns false, call stripThinkingConfig() immediately
regardless of the configured ThinkingMode
This is fully backward-compatible: models not in the denylist are unaffected,
and the supportsReasoning registry flag defaults to null (pass-through).
Fixes: HTTP 400 errors on antigravity provider when client sends requests
with thinking/reasoning budget parameters (e.g. claude-sonnet-4-6 via AG).
