chore: bump to v0.2.1

[tomcardoso]

What's new

• Import contacts exported from Gmail or Outlook. Sourcerer now recognizes a CSV file straight out of Google Contacts or Outlook and maps it to the right fields automatically — no need to reformat anything first. After an import, if your file included information Sourcerer doesn't track (like a mailing address or a spouse's name), you'll see a note listing what was skipped so nothing goes missing silently.
• Export contacts as a Gmail or Outlook CSV. Alongside the existing CSV/Excel and vCard export options, you can now export contacts (from All Contacts or from within a project) in a format ready to be re-imported directly into Google Contacts or Outlook.

Test plan

• npm version patch ran the full pre-release check (typecheck, lint, test suite — 547 tests) with no errors
• Manual testing of the new import/export flows in the running app
