Curl pauses security reports for July

This is a bold and healthy boundary-setting move that highlights the severe burnout and constant pressure faced by open-source maintainers.

* Open-source maintainers are humans first, and pausing security reports for a month to allow for actual rest is a highly logical step to prevent long-term project abandonment.

* Delaying the release of version 8.22.0 by two weeks is a small price for the community to pay to ensure the sustainability of curl's leadership.

* Pausing reports will likely lead to a backlog of vulnerability reports hitting the project on August 3, meaning the post-holiday period will require strong pacing to manage.

* While security researchers might find the delay inconvenient, it sets a great precedent for prioritizing open-source developer mental health over corporate expectations.
