docs(frank-zealot): re-key the exact-KV shape across the vault

AGENTS.md: topology row, the frank-zealot runbook section (shape, KV
accounting, MTP verdict, compaction-hub concurrency), and two Key
Lessons bullets -- the draft-context bill restated with the real knob
names, plus a new lesson that a quant's scale overhead belongs in its
byte rate (the 6.25 % invented by doubling 13,056.00 MiB).

LLM/frank-zealot-llama-prism-bonsai9-mtp.md: retitled to the live shape;
the 3-slot q8_0 boot ledger and its measurements are relabelled as the
arm this replaced (byte-identical numbers, honest attribution), the
corrected f16 rate derivation is added, the MTP census is labelled
q8_0-era, the fallback rungs are re-derived for the 524,288 pool, and the
boot-ledger section carries an explicit PROJECTION that must be replaced
with the measured ledger from the first f16 boot.

Pointers re-pointed (live-shape sentences only; every historical ledger
left byte-identical): LLM/index.md, vault index.md, Dankclaw/OpenWebUI.md,
and the retired-runbook "today" pointers in mimo-q5km, mimo-q6k,
qwen35-9b-q6k, swift15, sglang-mimo-v26. log.md gains the dated entry.
