fix(ai-client): add @standard-schema/spec to devDependencies

[AlemTuzlak]

Summary

Adds @standard-schema/spec to @tanstack/ai-client's devDependencies so TypeScript can follow through the InferToolInput / InferToolOutput chain at build time. Types-only dep — zero runtime cost.

Without it, @tanstack/ai-client's published .d.ts files reference types from @tanstack/ai that depend on StandardJSONSchemaV1, and the resolution silently degrades to any/unknown at the consumer site. That's what causes toolDefinition(...).client((input) => ...) to show input: unknown in user code.

Kept as a devDep intentionally — it's only needed during @tanstack/ai-client's own type checking / build, not shipped at runtime.

Fixes #235

Test plan

• pnpm test:types on @tanstack/ai and @tanstack/ai-client
• pnpm test:lib on both (198 tests on ai-client)

Summary by CodeRabbit

• Bug Fixes

  • Restored correct type inference for tool input/output and chat return types to avoid them resolving to unknown.

• Chores

  • Added a development dependency and updated workspace/configuration entries to support the fix.

• Release

  • Marked as a patch release.

📝 Walkthrough

Walkthrough

Adds @standard-schema/spec as a devDependency for the @tanstack/ai-client TypeScript package and records a changeset; also updates knip.json to ignore that dependency. Changes target build-time type resolution for tool input/output inference.

Changes

Cohort / File(s)	Summary
Changeset Entry ​.changeset/fix-standard-schema-dependency.md	Adds a new changeset declaring a patch release for @tanstack/ai-client that documents adding @standard-schema/spec to devDependencies.
Package Configuration packages/typescript/ai-client/package.json	Adds @standard-schema/spec@^1.1.0 to devDependencies. No public API or runtime code changed.
Lint/Tooling Config knip.json	Adds a workspace entry for packages/typescript/ai-client with ignoreDependencies: ["@standard-schema/spec"] to avoid knip warnings for the new devDependency.

Poem

🐇 I found a spec to help types bloom,
No more unknowns in the typing room,
Dev deps added, tidy and neat,
Tool inputs now match — oh what a treat! 🥕

Check name	Status	Explanation
Title check	✅ Passed	The title accurately and concisely describes the primary change: adding @standard-schema/spec to devDependencies for the ai-client package.
Description check	✅ Passed	The description is comprehensive, explaining the motivation, rationale, and testing performed; however, the checklist items are not explicitly marked as completed.
