Aggiunge il modulo `multi_swarm.protocol` con la grammatica del DSL di strategia (15 verbi: 4 azioni, 3 logici, 3 comparatori, 4 dati, `when` e `strategy`) e un parser che produce un AST tipizzato (Strategy/Rule/ Node). Lessing delegato a sexpdata, validazione del set di verbi e forma `(when <cond> <action>)` gestita dal parser. Sollevata ParseError su top-level malformato, strategia vuota, verbi sconosciuti o azioni non terminali. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
