fix(ai): move @standard-schema/spec to dependencies

[AlemTuzlak]

Summary

• Move @standard-schema/spec from devDependencies to dependencies in @tanstack/ai
• Without this package installed by consumers, all types that depend on StandardJSONSchemaV1 silently degrade to any — tool definitions lose type inference, chat() return types become any
• This is a zero-runtime-cost fix (types-only package) that ensures consumers get correct type resolution transitively

Fixes #235

Test plan

• pnpm test:types passes
• pnpm test:lib — all 631 tests pass
• pnpm build succeeds

Summary by CodeRabbit

• Chores
  • Moved standard schema support to runtime dependencies so consumers receive full type information and tool inference, preventing degraded types and loss of inferred return/response types.
  • Added a changeset to record this adjustment and trigger a patch release.

Poem

🐰 I hopped through code with twitchy glee,
The spec moved home where all can see,
Types now travel, neat and free,
Tools hum true — a rabbit's tea! ☕✨

🚥 Pre-merge checks | ✅ 5

✅ Passed checks (5 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title accurately and concisely describes the main change: moving @standard-schema/spec to dependencies in the AI package.
Description check	✅ Passed	The description covers the main changes and includes a test plan, but omits the required checklist sections from the template.
Linked Issues check	✅ Passed	The PR fully addresses issue #235 by moving @standard-schema/spec to dependencies, which ensures tool definition types correctly infer without degrading to any.
Out of Scope Changes check	✅ Passed	All changes are directly scoped to fixing the type inference issue; only package.json and changeset file were modified.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
