Add capsules/sdk.4th: SDK v1.9.0 vocabulary + FENCE over the cookbook capsules

Browse Source 
Loads turtle.4th and doe.4th, defines SDK-VERSION/SDK-HELP into an SDK
vocabulary, then calls FENCE once everything is loaded -- protecting the
base wordset and both cookbook capsules from FORGET. Kernel-only (EXEC
doesn't exist hosted), REPL-invoked via S" sdk.4th" EXEC, not part of
init.4th's boot sequence.

Verified before writing the capsule, not assumed: VOCABULARY/DEFINITIONS
does not actually scope word visibility in this interpreter -- vm_find_word
is a flat dictionary scan that never consults CONTEXT/CURRENT. Documented
plainly in the HOWTO so this isn't mistaken for namespace isolation later.

Block range 5109-5115 -- discovered along the way that user-block space is
capped at [2048, 5120) by mkcapsule, tighter than expected.

Verified: mkcapsule --lint clean, hosted-build trace runs SDK-HELP with
zero attributable VM errors, zero build warnings and identical 1012/0/0
POST results with matching dict_hash on all three kernel architectures.

HOWTO: docs/working/architecture/SDK-HOWTO-20260819.md
