Added

• AccessRuleSet policy schema with rule matching (sourceClientId, targetClientId, HTTP methods, URI patterns) and optional CEL condition.
• kmctl authz validate — structural and CEL syntax validation.
• kmctl authz simulate — runs scenarios against a policy and reports pass/fail.
• kmctl authz explain — per-condition trace for both GRANT and DENY outcomes.
• Numeric coercion across Integer/Short/Byte/BigInteger/Float/BigDecimal into CEL Long/Double.
• Thread-safe pattern caching in the rule matcher.
