Drop Sonnet 4.6, add Sonnet 5

[nikships]

Summary

Replaces the Claude-provider Sonnet 4.6 model with Sonnet 5 (claude-sonnet-5).

• Catalog entry now exposes the full reasoning level set (low/medium/high/xhigh/max, default xhigh) with a 128000 output ceiling, matching Opus 4.8.
• Sonnet 5 supports output_config.effort: max natively, so the Sonnet 4.6-only max-thinking workaround in ThinkingProxy (which rewrote max requests into classic thinking:{type:enabled,budget_tokens} and pinned max_tokens) is removed.

Changes

• DroidProxyModelCatalog.swift — claude-sonnet-4-6 → claude-sonnet-5 (slug sonnet-5, "Sonnet 5"), maxOutputTokens: 128000, claudeAdvancedLevels, default xhigh. Removed the unused claudeSonnetLevels static.
• ThinkingProxy.swift — deleted the max-thinking call site, constants, and the applySonnetMaxThinking / sonnetRequestsMaxEffort / pinSonnetMaxThinkingMaxTokens helpers; updated the class doc comment.
• Tests — removed ThinkingProxySonnetMaxThinkingTests.swift; updated the catalog test for Sonnet 5.
• AGENTS.md — updated the Claude thinking reference to Sonnet 5.

The separate Antigravity ag-c46s-thinking ("Claude Sonnet 4.6 (Thinking)") entry is unchanged.

Verification

swift build and swift test both pass (17 tests, 0 failures).

Code Review

This pull request upgrades the supported Claude Sonnet model from version 4.6 to version 5. Key changes include updating the model identifier to claude-sonnet-5, doubling the maximum output tokens to 128,000, and setting the default reasoning effort to xhigh. It also removes the legacy workaround logic and associated tests for Sonnet 4.6's max-thinking effort level, as Sonnet 5 natively supports the full range of advanced thinking levels. I have no feedback to provide.

📝 Walkthrough

Summary by CodeRabbit

• New Features

  • Updated the supported Claude adaptive model to a newer Sonnet release with higher output limits and a higher default reasoning level.

  • Refreshed the supported reasoning options to include the newest higher-effort settings.

• Documentation

  • Updated the model/behavior notes to match the latest supported Claude versions.

Walkthrough

Removes Sonnet 4.6-specific max-thinking JSON transform logic from ThinkingProxy.swift (call site, helpers, constants), replaces the Sonnet 4.6 model catalog entry with a Sonnet 5 entry using updated tokens and reasoning levels, and updates tests and docs to match.

Poem

🐇 Sonnet four-point-six, farewell, goodbye,
No more max-thinking transforms on the fly.
Sonnet Five hops in with xhigh in its name,
128k tokens — a much bigger game!
The rabbit clips the old wires, clean and neat. ✂️
