fix(deps): bump zod to 4.4.3 to satisfy @openrouter/ai-sdk-provider peer

[AndreyHirsa]

Summary

Bump zod from 4.1.12 to 4.4.3 across cli, compiler, sdk, and spec so it satisfies the zod@^4.3.5 peer requirement of @openrouter/ai-sdk-provider@6.0.0-alpha.1, fixing npm install failures under strict-peer-deps and eliminating duplicate zod installs on the default install path.

Changes

• Bump zod 4.1.12 → 4.4.3 (exact pin, per the no-^/~ policy) in packages/cli, packages/compiler, packages/sdk, and packages/spec.
• All four are bumped/released together: @lingo.dev/_compiler independently carries the @openrouter/ai-sdk-provider alpha, and cli depends on the workspace siblings — releasing them in lockstep keeps a single satisfying zod version across the published closure.

Testing

Business logic tests added:

• N/A — dependency-version bump only, no behavior change (the code uses core, stable zod APIs unchanged across 4.x)
• N/A — no new edge cases introduced
• All tests pass locally

Additional verification (manual):

• published 0.137.7 + strict-peer-deps=true → ERESOLVE.
• Packed the fixed artifacts and installed them with strict-peer-deps=true → clean install, single zod@4.4.3.
• Default npm install (no strict): broken version silently installs two zod copies (4.4.3 + 4.1.12); fixed version resolves to a single zod@4.4.3.
• npm audit on zod@4.4.3 → 0 advisories; zod has no runtime dependencies.
• syncpack lint-semver-ranges (the prebuild gate) → ✓ 297 valid.

Visuals

N/A

Checklist

• Changeset added (if version bump needed)
• Tests cover business logic (not just happy path) — N/A, dependency bump with no logic change
• No breaking changes (or documented below)

Closes #[issue-number]
