fix: recognize workspace-root Intent devDependency

[LadyBluenotes]

🎯 Changes

Stacked on #265. Fixes #212.

Recognize @tanstack/intent in the owning workspace root's devDependencies when validating a member package. Keep package-local declarations valid and preserve the warning when Intent is declared only by a sibling package. Package keywords and publishing checks still use the member's manifest.

Regression tests cover package.json and pnpm workspace declarations, invocation from the workspace root and member directory, and removal of the root declaration.

Verification: all 146 CLI tests passed; package typecheck, focused ESLint, Prettier, and git diff --check passed. Three existing lint warnings remain. No dependency, guide, or CI changes.

✅ Checklist

• I have followed the steps in the Contributing guide.
• I have tested this code locally with pnpm run test:pr.

🚀 Release Impact

• This change affects published code, and I have generated a changeset.
• This change is docs/CI/dev-only (no release).
