Kjell Tore Guttormsen f926071348 fix(llm-security): compileRules coerces a non-string pattern instead of dropping the rule 
new RegExp(pattern, 'i') never throws when pattern is a truthy non-string
(e.g. an object) — it ToString-coerces it first. The truthy-only guard
(`!rule.pattern`) let such a rule through as a real, compiled RegExp,
bypassing the try/catch meant to drop malformed rules. Worse than a silent
drop: `new RegExp("[object Object]", "i")` is parsed as a character class
over o/b/j/e/c/t/space, so the "dropped" rule instead becomes a
near-universal false-positive matcher. Same path for the built-in
commons-backed ruleset and the operator's sig.custom_rules_path (both
route through compileRules).

Fix: require typeof rule.pattern === 'string' before compiling. Verified
the golden dump pins no rule that exists only because of this coercion —
it regenerates byte-identically after the fix.
