chore: update version to 2.0.2

[StefanoGuerrini]

Summary

Version bump to 2.0.2 following the historical pattern (direct edits to the two package.json files).

Release notes (for the GitHub Release body)

• Fix (fix: off-by-one in retryOn — retries: 0 still retries once #14, Default retries: 0 still performs one retry on 422/503/504 #15): retries: 0 (the documented default of "no retries") now actually performs zero retries. Previously, off-by-one in the retryOn callback caused one extra fetch on 422/503/504 responses. Callers on defaults will see ~1 fewer request per transient failure. Thanks @jorgehermo9 for the report and fix.

Notes

• examples/package-lock.json intentionally not refreshed here — the 2.0.2 tarball doesn't exist on npm yet. Refresh that in a small follow-up after publish (cd examples && npm install).
• New release workflow (chore: add release workflow (publish on GitHub Release) #18) will trigger on the GitHub Release for v2.0.2 and publish to npm. Requires NPM_TOKEN repo secret to be in place first.

Test plan

• Both package.json files bumped to 2.0.2
• examples/ dependency range bumped to ^2.0.2
• CI green on this PR
• After merge: create GitHub Release v2.0.2 with the notes above → release workflow publishes
