chore(deps): autoupdate (needs claude fix)

[github-actions]

The dependency autoupdater failed during builds-and-checks.

Run log: https://github.com/dudko-dev/protoobject/actions/runs/31849984081

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 run test:ts

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.

[claude]

All green on first run — no fix needed.

• npm install --no-audit --no-fund: exit 0
• npm run lint: exit 0
• npm run build: exit 0
• npm run test:ts: exit 0 (5/5 tests passed)

The only diff on this branch vs main is the dependency bump (@sergdudko/objectstream ^4.0.44 → ^4.0.45) plus the version bump to 2.1.48 in package.json/package-lock.json, both already present from the autoupdate commit. No compatibility issues found, so no commits were pushed.
