chore(lexicon): cap remaining unbounded strings per goat lint; add publish runbook master

goat lex lint flagged 77 string fields with no maxLength across params, outputs, and knownValues tokens. Cap them all (cursors 500, knownValues 64, plus per-field caps for email/password/JWTs/api-keys/search queries). Remaining large-string warnings are intentional (base64 image fields, long-form content at the 10:1 grapheme ratio). Add docs/LEXICON_PUBLISHING.md (publish/hold-back sets, decisions log, workflow) and scripts/publish-lexicon-dns.sh (idempotent Cloudflare API upsert of the 9 _lexicon TXT delegations; moderation deferred via flag).
