Note

Medium Risk
Adds a hardcoded license key bypass in validation logic; if misused or left in production it can undermine licensing enforcement.

Overview
License validation now treats an additional hardcoded trial key as always valid. Specifically, checkLicenseKeyValidity in licenseKeyValidator.ts whitelists hftrial-0168e-1f2b7-47158-70b05-0842f alongside the existing special-case keys, bypassing schema/expiry checks for that value.

Trial license key never expires, behaves as permanent

High Severity

The new hftrial-… key is placed in the same branch as gpl-v3 and internal-use-in-handsontable, which unconditionally sets the state to VALID without any expiration check. Unlike schema-validated keys that go through date-based expiry logic, this trial key will be valid forever, defeating the purpose of a "trial" license.
