FABRIC.md: item 4.5f -- reorder experiment confirms -O2 fixes the stall

Browse Source

Uncommitted experiment (code reverted after capture, per Captain Bob):
moved console_fb_init() before capsule_birth_mama() in kernel_main.c,
amd64 only. At -O2 the boot completes cleanly and reaches ok> well
inside a 300s bound, versus the indefinite stall previously seen at
-O0. Real cost: ~12x more heartbeat ticks during boot from the extra
framebuffer scroll volume -- not free, but not a hang.

Screendump confirms the actual point of 4.4g: the framebuffer now
carries the full HADES/ECW/Stadium/self-test transcript, not just the
small post-birth tail.

This informs 4.4g's open reorder decision, it doesn't make it -- 4.5f
stays unchecked (single-arch feasibility check only, not the three-arch
acceptance pass its own done-when requires).
