feat(ai-sdk): re-export @supermemory/tools/ai-sdk

[haroon0x]

Deprecate the duplicated implementation in @supermemory/ai-sdk (2.0.0). The package now re-exports @supermemory/tools/ai-sdk and inherits its container-scoping and coercion semantics. Drops the stale deps that pinned @ai-sdk/provider@2 at the root, adds it back with the v3 range (its d.ts requires v3 types), and adds a turbo edge so check-types builds tools' dist first.

Closes #1247

@supermemory/ai-sdk 2.0.0 is now a thin re-export of @supermemory/tools/ai-sdk. The duplicated implementation (src/tools.ts, ~150 lines, plus its tests) is deleted.

What changed

• Scoping: passing both projectId and containerTags now throws; no config defaults to ["sm_project_default"].
• Coercion: limits arrive as numbers even when the model emits strings.
• Deps: dropped the stale pins (ai, @ai-sdk/openai, supermemory, @ai-sdk/provider@^2.0.0) that forced provider 2.x to the root. Added @ai-sdk/provider@^3.0.0 back on purpose: tools' types reference v3-only types, and pnpm resolves the tools peer to the lowest match, which broke consumer typechecks without it.
• tools: the @ai-sdk/provider peer range is narrowed from ^2.0.0 || ^3.0.0 to ^3.0.0. The ^2 side was never typecheckable against the published .d.ts.
• tsdown config: stable .d.ts filenames and an exports block with a types condition (hashed names broke nodenext type resolution). exports: false is explained in the config.
• CI: check-types now builds tools' dist first via a Turbo edge. dist/** joined the build outputs so that build is cacheable. The publish workflow builds from the repo root.

Why 2.0.0

A major because the default scope and coercion semantics differ from 1.x. The export surface is a strict superset of 1.x.

Verified

• Packed tarballs installed into fresh npm and pnpm consumers: exports, scoping, coercion, and a strict nodenext typecheck pass.
• Repo CI gates (ai-sdk + memory-graph check-types) pass under the pinned Bun 1.3.6.

Closing this one. Four PRs are open for the same consolidation, so we are keeping #1433 as the single thread since it also refreshes the tool surface.

Worth flagging for whoever picks this up: packages/ai-sdk/src/tools.ts now holds a search-limit clamp added in #1593, and packages/tools/src/ai-sdk.ts has no equivalent. Collapsing the package into a re-export today would silently drop that bound, so the clamp needs porting across first.
