ci(workflows): pin pnpm version via packageManager field

[kitsunoff]

What

Add "packageManager": "pnpm@10.26.0" to the root package.json.

Why

The test workflow added in #5 has been failing on every run with
No pnpm version is specified — pnpm/action-setup@v4 requires either
a version: input on the action or a packageManager field in
package.json. The latter is the preferred declaration because it
also pins the version for local developers, not just CI.

Verification

• pnpm install --frozen-lockfile — clean
• pnpm typecheck — clean
• pnpm test — 29/29 passing

Once merged, the test check should go green on main and on
subsequent PRs.

Code Review

This pull request adds the packageManager field to package.json. The review feedback correctly identifies a syntax error due to a missing trailing comma and points out that the specified pnpm version is invalid, providing a code suggestion to resolve these issues.

[gemini-code-assist]

This line is missing a trailing comma, which makes the package.json file invalid JSON. Any subsequent pnpm or npm commands will fail due to this syntax error.

Additionally, the specified pnpm version 10.26.0 does not appear to be a valid, publicly released version. This will likely cause the CI to fail when pnpm/action-setup tries to download it, as it won't be found in the official pnpm releases.

Please add the comma and use a valid pnpm version to fix both issues.

Suggested change

	"packageManager": "pnpm@10.26.0",
