* feat(ast): add LoopKey to TemplateContext for dictionary iteration * feat(ast): add @key loop variable to ExpressionEvaluator * feat(ast): add ObjectValue iteration to TemplateExpander * feat(ast): add ObjectValue iteration to inline {{#each}} blocks * feat(ast): trim keys in SetLoopKey to ensure clean @key values * feat(ast): trim keys in ObjectValue for consistent key handling * feat(ast): add computed key access [expr] to expression system Add IndexAccessExpression AST node, Pratt parser postfix operator for bracket notation, and evaluator support for dynamic key/index access on ObjectValue and ArrayValue. * test: add end-to-end integration tests for dictionary iteration with computed key access Add scope walking to ExpressionEvaluator.Resolve so variables from parent scopes (e.g. root data) are accessible inside each loops. This enables patterns like {{values[@key]}} where @key comes from the loop and values lives at root level. * docs: fix inverted XML doc comment on TemplateContext.Scopes * docs: add dictionary iteration and computed key access to wiki
