chore: bump version to 1.6.0

[felipefreitag]

Release PR for v1.6.0, covering the two features merged since v1.5.0.

Changes

• Bump Resend::VERSION to 1.6.0 and sync the Gemfile.lock pin.
• Add a CHANGELOG.md entry for 1.6.0 (reviving the changelog, which had been dormant since 1.0.0 — scoped to this release only).

Included in this release

• OAuth grants — Resend::OAuthGrants list + revoke (feat: add OAuth grants support #197)
• Domain claims — Resend::Domains::Claims create/get/verify (feat: add domain claims endpoints #194)

Release steps (post-merge)

Once merged, a maintainer with RubyGems push access runs from main:

bundle exec rake release

This builds the gem, tags v1.6.0, and pushes to rubygems.org.

Testing

• bundle exec rspec → 310 examples, 0 failures
• bundle exec rubocop → no offenses

• In CHANGELOG.md, the missing [1.6.0] reference link can leave release notes navigation incomplete, which may confuse users trying to view the full diff, but it does not pose runtime or regression risk — add the [1.6.0] compare link in the same format as existing entries before or immediately after merge.
