chore(release): bump version to 0.2.1 (#256)

## Summary
Patch release shipping #255, which unbreaks `bugs list --status
resolved|dismissed` and `bugs show` for reviews sourced from the
backend's new `jira`, `github_issue`, and `bug_fix_check` integrations.

On merge, the release workflow will tag `v0.2.1` and publish platform
artifacts via cargo-dist.

## Test plan
- [x] `cargo build` succeeds with version 0.2.1
- [ ] Tag `v0.2.1` is created on merge and release workflow publishes
artifacts
