feat: extend guard parser with >=/<=/bare bool/negation#78
Merged
Conversation
Fix guard parser to handle >=, <= operators (split_once bug), bare boolean identifiers as IsTrue shorthand, and !var/is_false negation. Full stack: spec parser → translate → JIT runtime → verify model → SMT. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Moves tests to toml_parser_tests.rs to keep toml_parser.rs under the 1000-line readability ratchet threshold. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
>=/<=operator parsing —split_once('>')was mis-splitting>=, corrupting variable names. Now checks 2-char operators before 1-char (same pattern as assert_parser.rs).guard = "has_mutation"now works as shorthand foris_true has_mutation.!var,is_false var, and{ type = "is_false", var = "..." }all produce the newIsFalseguard variant, propagated through the full stack (spec → translate → JIT → verify → SMT).Test plan
