Adds specs/eish_zarah_reading.md — chavruta analysis of eish zarah
(strange fire) as architectural concept. Identifies five patterns across
fiction canon (inaccessible source, restructuring gift, false god,
false unity, beautiful unchecked signal), maps to Torah structures,
and evaluates eight specific implementation gaps in the Shorashim system.
Key gaps identified: coupling trace (interpret.pl needs L1 grounding
field), self-reference loop (resolve.pl feeds own output without
detection), three forms of avodah zarah (only Form 1 implemented),
panim/achorai distinction (challenges don't mark text vs. inference),
severed floor (raw Korban not stored alongside processed).
Updates construction spec document registry.
