Move fabric.4th + font.4th to hestia/init.4th -- FABRIC-3.6.md tasks 1.6+1.7 (merged)

Tasks 1.6 and 1.7 are not independent, and the punchlist's split was
wrong: font.4th calls G-LINE/G-ELLIPSE, which are fabric.4th's own
words. Confirmed live before committing to an approach -- removed only
fabric.4th's EXEC from init.4th, left font.4th's in place, booted
amd64: Hera's boot floods with UNKNOWN WORD: 'G-LINE'/'G-ELLIPSE' the
moment font.4th loads (logs/20260919-171047/amd64/, kept as evidence).
Reverted that partial state, asked Captain Bob how to proceed given
neither task can independently pass its own three-arch-boot check, and
was told to use best practices.

Moved both together, in their original relative order, into a new
capsules/hestia/init.4th block 4988 -- a deliberate, documented
deviation from "one task, one commit," not a bundling of convenience.

Three-arch boot clean: amd64/aarch64/riscv64 all reach [zuse@Hera] ok>,
zero UNKNOWN WORD. Hestia's dict_hash identical across all three
architectures. Verified the shrink/grow live, not just inferred from
hash movement: HERE reads 20008 in Hera, 63040 in Hestia post-move.
CART-PLOT in Hera is UNKNOWN WORD; the identical call routed into
Hestia via VM-EXEC reaches the word and fails on a stack underflow
instead, proof it exists there since an unknown word can't underflow.

mkcapsule --lint capsules/ clean, 38 files / 0 violations. MANIFEST.md
updated: init.4th's block 2049 entry no longer lists fabric.4th/
font.4th; hestia/init.4th's entry gains block 4988.

Authorized by Captain Bob ("Use best practices.").
