chore(deps): autoupdate (needs claude fix)

[github-actions]

The dependency autoupdater failed during builds-and-checks.

Run log: https://github.com/siarheidudko/objectstream/actions/runs/30672705084

A Claude session has been dispatched to push fixes onto this branch
so the following commands all exit 0:

  npm run lint
  npm run build
  npm test

Claude will leave a status comment on this PR when it finishes.
The Claude workflow re-dispatches PR-checks once it is done, so the
checks below reflect its pushed fixes.

Autoupdate fix status

• npm install --no-audit --no-fund failed initially with an ERESOLVE conflict: the autoupdater bumped typescript to ^7.0.2, but typescript-eslint@8.65.0 (latest published) still requires typescript >=4.8.4 <6.1.0. No typescript-eslint release currently supports TS 7.

Fix: pinned typescript back to ^6.0.3 in package.json (and regenerated package-lock.json), matching the same compatibility shim applied in two prior autoupdate PRs (#25, #26) for this exact issue. No product logic changed, no version bump.

After the fix, all three gating commands are green:

• npm run lint — exit 0
• npm run build — exit 0
• npm test — exit 0 (48/48 tests passed)

Pushed commit 1dfb80b to chore/autoupdate-30672705084.
