aieo 0.2.0 + mcp: bump to AI SDK v7

[Evanfeenstra]

Moves aieo and mcp to ai 7. aieo 0.2.0 is already published from this branch. mcp now pins strut to the v7 merge (stakwork/strut#11, eda56a5).

aieo 0.2.0

• Requires ai ^7 as a peer. Bundled providers: @ai-sdk/anthropic/openai/google 4, xai 5, @openrouter/ai-sdk-provider 3. Needs Node 22 or later.
• Builds ESM only, because ai v7 dropped CommonJS.
• callModel: system → instructions, fullStream → stream. callGenerateObject: generateObject → generateText + Output.object.
• store.ts uses crypto.randomUUID() in place of uuid. aieo never declared uuid; the import only worked because the monorepo hoisted it.

mcp dependencies

• ai 7.0.105, @ai-sdk/anthropic 4, @ai-sdk/mcp 2, @ai-sdk/provider 4, zod 4.6.5. gitsee/agent is pinned to the same versions.
• Removed the global ai/@ai-sdk resolutions. They forced ai 6 onto stagehand (which declares ai 5) and onto gitsee. Those packages now get their own nested copies. mcp, aieo, gitsee-agent, strut and the MCP SDK still share a single root ai and zod, which is what bump strut + aieo 0.1.42: zod / ai as peerDependencies — one copy per process #1682 needs.

The change that matters

In v7, each step's response.messages holds only that step's messages, and a result's response covers only the final step. Code that relied on the v6 behavior still compiled, and it would have lost data at runtime:

• extractMessagesFromSteps read only the last step, which relied on v6 making it cumulative. Sessions saved by the repo agent, explore, logs, and graph_sub_agent error recovery would have kept only the final step. Replaying those sessions produces orphaned tool_use blocks. It now joins every step's messages.
• repo/agent.ts (3 places) and the gitsee lab read response.messages for continuations and concept reflection. They now read responseMessages.

Tests

• New extract-messages-from-steps.test.ts runs a real 2-step tool loop on v7's mock model. It fails against the old last-step logic.
• The toolsJarvis recovery tests check an inline copy of the function. That copy is updated to v7's per-step behavior.
• tsc: 0 errors. test:node: 798/798. aieo: 99/99.
• Live run against Haiku: callModel with a system message, callGenerateObject, and a 2-step tool loop, whose transcript came out as user, assistant, tool, assistant.

Not in this PR

• Deprecated names that v7 still accepts (system, onStepFinish, totalUsage, generateObject, stepCountIs, image parts, toUIMessageStreamResponse). npx @ai-sdk/codemod v7 can clean these up in a follow-up.
• Publishing gitsee-agent. Its dependencies changed, but its version is still 1.0.19 so mcp keeps using the local workspace copy.
