Add attacker-alignment modifier conditions (attacker_is_evil/lawful/good/
chaotic) evaluated against an optional attacker context threaded through
_stat_modifiers/_modifier_condition_holds, _attack_ac_mods (resolve_attack
AC path), resolve_save and _area_save (spell save paths), plus the fear
aura. Without a source in scope the condition is False, so existing rolls
are untouched (golden transcripts bit-identical).
Give the four protection_from_evil/law(+communal) JSONs their SRD buff:
+2 deflection to AC and +2 resistance on fort/ref/will, gated on the
attacker/caster alignment (SRD: bonuses apply 'against attacks or effects
created by evil creatures'); duration 1 min/level approximated as 10
rounds (engine convention). Descriptions document the unmodeled mental-
control suppression and communal duration-split clauses. Level/range/
save/SR verified against the KB.
SpellSpec gains spell_resistance: bool = True (JSON 'spell_resistance'). When false, _spell_delivery_blocked skips the targeted SR check and _apply_area_effect skips the per-creature SR check (threaded through the effect chain). Verified each imported spell against the local KB and set false on the 28 whose SRD block says 'Spell Resistance: no' (Acid Arrow, Flurry of Snowballs, Web, Darkness, Sanctuary, the Protection from X spells, etc.). Added no-SR targeted/area tests and a high-SR control in test_spell_resistance.py, and the README.
