feat: Upgrade Claude adapter to SDK 0.3 with native binary

[charlesvien]

Problem

It's that time of the month again, claude adapter update! We pinned the adapter to SDK 0.2.112 for awhile because 0.2.114 broke session init; meanwhile upstream shipped Task tools, MCP changes and ACP 0.22. Lots of bug fixes + supposed session initialization timing improvements being adopted.

Changes

1. Bump claude-agent-sdk 0.2.112 -> 0.3.144, ACP SDK 0.19 -> 0.22.1, anthropic SDK 0.89 -> 0.96
2. Port TodoWrite -> Task tools migration with a per-session task map and TaskCreated/TaskCompleted hook handlers
3. Switch session resume to the new resumeSession API (was unstable_resumeSession) for ACP 0.22
4. Set MCP_CONNECTION_NONBLOCKING=0 so MCP servers stay blocking-connect and tools are ready on first prompt
5. Ship native Claude binary in the bundle and harden vite packaging for cross-arch macOS/win/linux builds
6. Add unit tests for hooks, models, settings, and task-state conversion

How did you test this?

T-Rex Logs

What T-Rex did

• Ran native Claude binary resolution across platform and architecture inputs, including Windows binary naming and Linux libc candidate ordering.
• Ran TaskCreate and TaskUpdate plan-state conversion checks, including missing output, deleted tasks, ordering, and text-block parsing.
• Checked task hook ordering and duplicate handling for TaskCreated and TaskCompleted events.
• Ran MCP server parsing checks for http, sse, stdio, and unsupported sdk-type entries.
• Checked model alias resolution, capability gating, and local-command marker stripping behavior.

Artifacts

Comprehensive proof-of-work results

• Aggregates logs and results covering binary resolution, task state conversions, hook ordering, MCP config parsing, and model resolution checks to help verify the code-execution checks.

Task state conversion checks

• Keeps the command output available without making the summary code-heavy.

Task hook ordering checks

• Keeps the command output available without making the summary code-heavy.

MCP config parsing checks

• Keeps the command output available without making the summary code-heavy.

Model resolution checks

• Keeps the command output available without making the summary code-heavy.

Local command marker stripping checks

• Keeps the command output available without making the summary code-heavy.

• Bug
  • applyAvailableModelsAllowlist was checked with a gateway default of claude-opus-4-7 and availableModels: "claude-haiku-4-5".
  • The returned model options dropped the gateway Default option entirely.
  • The returned currentModelId changed to the first allowlisted model instead of preserving the default/current model.
  • This contradicts the function comment and Claude Code behavior that the Default model remains available even when availableModels is configured.
• Cause
  • T-Rex reproduced this while running the changed behavior, but it did not return a separate root-cause sentence.
• Fix
  • Update the changed code so this failing path is handled, then rerun the same T-Rex check to confirm it passes.

Artifacts

availableModels allowlist repro

• Keeps the command output available without making the summary code-heavy.
