bigdei_kodesh: disclose origin + not-horaah on every Torah-content response

Three Torah-grounded concerns at the user boundary:
- kichush (Vayikra 19:11) — origin not disclosed to recipients
- horaah (Devarim 17:8-11) — disclaimer present only at /chatzer/sanhedrin
- lo yachel devaro (Bamidbar 30:3) — external API terms unacknowledged

router.ex: disclosure/0 helper attached to every Torah-content response
(/peah, /courtyard, /chatzer/sanhedrin, teiku error). origin states the
system reasons computationally and may incorporate processed external-AI
output. not_horaah states the result is not a binding ruling. torah_basis
cites the verses.

shorashim_tamid.md: §7 EXTERNAL NEDARIM. Bamidbar 30:3 with translation,
Rambam cross-reference to mitzvot.pl (#93, #308, #542, #543),
Avraham–Avimelekh precedent for non-Israelite-party covenants, operator
responsibilities, Anthropic-specific posture, and separation between the
system's avodah_zarah halt and the operator's lo-yachel covenant.
