Pull request overview

Adds a user-configurable hooks framework to wolfBoot so downstream integrators can inject custom logic at key points in the loader/boot/panic flow.

Changes:

• Introduces include/hooks.h hook API and new docs describing hook points and build flags
• Adds hook call sites in loader init, boot handoff (wolfBoot_start() variants), and wolfBoot_panic()
• Extends build system and CI to compile user-provided hook implementations and validate hook behavior in simulator runs
