refactor: align delete method with other HTTP methods in Resend class

[wesleyramalho]

The delete method was inconsistent with post, get, put, and patch — it didn't support custom headers/options and unconditionally stringified the body even when undefined. Now follows the same pattern.

Summary by cubic

Aligns the delete method with other HTTP methods in Resend by adding options/header support and only sending a body when provided. Uses a strict undefined check to preserve valid falsy payloads.

• Refactors

  • Added and exported DeleteOptions interface.
  • delete() accepts options, merges custom headers with defaults.
  • Only stringifies query when defined; omits body otherwise.

• Bug Fixes

  • Use === undefined check so null, 0, "", and false are sent correctly.

Confidence score: 3/5

• There is a concrete regression risk in src/resend.ts: DELETE body serialization now uses a truthiness check on query, which can drop valid falsy payloads (for example 0 or false).
• Given the 5/10 severity with high confidence (9/10), this is a moderate user-impacting behavior change rather than a merge-blocking failure, so the PR carries some risk.
• Pay close attention to src/resend.ts - ensure DELETE request body handling preserves intentionally provided falsy values.
