Prepare 6.8.7 Release

[cbravobernal]

Release Date 8th June 2026

Fixes

• SCF's Abilities API integration for its internal post types no longer triggers PHP warnings, notices, or a fatal error (500) on block editor and REST API requests when another active plugin builds the WordPress abilities registry earlier in the request; registration is skipped cleanly in that case and normal abilities behavior is otherwise unchanged.
