Implements a new CreateRelease tool following the existing pattern used by CreateRepository and other create operations. Features: - Creates GitHub releases with tag name, target commitish, and release notes - Supports draft and prerelease flags - Supports automatic release notes generation - Comprehensive test coverage following existing test patterns Closes github#1012
Addresses Copilot review comment - the response body was being closed before attempting to read it in the error case. Now we only close it after reading when needed.
Put single defer statement right after successful API call to ensure body is closed in all paths. Removes duplicate defer statements.
