chore: sync package.json version to 0.0.48

[cablate]

Summary

• Previous release published 0.0.48 to npm but failed at MCP Registry step
• The version bump commit never landed on main (package.json still says 0.0.47)
• This syncs package.json to 0.0.48 so the next release will correctly bump to 0.0.49

Note: Commit message starts with chore: release so the release workflow will skip this merge (matching the existing skip condition).

Test plan

• Next merge to main won't trigger release (skipped by chore: release prefix)
• Next feature merge will bump to 0.0.49 and publish successfully
