15 of mama_forth_words.c's 48 silent sites fixed, split by functional
grouping per direct instruction: CAPSULE@/CAPSULE-HASH@/CAPSULE-FLAGS@/
CAPSULE-LEN@/CAPSULE-BIRTH/CAPSULE-RUN/EXEC (9), and BIRTH/START/KILL
(6).
Refined the diagnostic-placement rule: match whichever convention that
same function's other already-correct guards use, rather than
defaulting uniformly. BIRTH/START/KILL/EXEC each already had a
console_println() sibling guard ("name too long or empty") -- their
newly-diagnosed guards now match that, same shape as USE's own fix.
The CAPSULE*@ words have no sibling guard to match, so they keep
log_message() (defer_words.c's gold-standard default).
Three-arch clean qemu acceptance passed; BIRTH itself is exercised by
every boot (Hermes/Artemis birth).

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
